| 27 Based on code from pre-release FSF 19, c. 1991. | |
| 28 Various changes by Jamie Zawinski 1991-1994: | |
| 29 converting to ANSI C, splitting out function prototypes to a separate | |
| 30 file (later moved back for unknown reasons by Steve Baur?), debug-gcpro | |
| 31 stuff (now moribund). | |
| 32 ANSI-fication of DEFUN macros by Felix Lee, c. 1992? | |
| 33 NOT_REACHED, DOESNT_RETURN, PRINTF_ARGS by Richard Mlynarik, c. 1994. | |
| 34 Many changes over the years corresponding to Lisp_Object definition | |
| 35 changes, esp. by Richard Mlynarik (c. 1993) and Kyle Jones (c. 1998). | |
| 36 See alloc.c for more details. | |
| 37 Overhauled and reordered by Ben Wing, 1995-1996, and many things added: | |
| 38 Dynarrs, REALLOC macros, asserts, typedefs, inline header code, | |
| 39 first LIST_LOOP macros, CONCHECK_*, all error-checking code | |
| 40 (e.g. error-checking versions of XFOO macros), structure read syntax, | |
| 41 weak lists, lcrecord lists, reworking of quit handling, object hashing, | |
| 42 nested GCPRO, character objects and Ebola checking, memory usage stats, | |
| 43 others. | |
| 44 LOADHIST changes from Steve Baur, c. 1997? | |
| 45 Various macro-related changes by Martin Buchholz, 1998-1999: | |
| 46 LIST_LOOP macros greatly expanded and tortoise-hared; | |
| 47 RETURN_SANS_WARNINGS; reworked DEFUN macros; EXFUN macros (???). | |
| 1743 | 48 Various macro-related changes by Jerry James, 2003: |
| 49 MODULE_API introduced; | |
| 50 Compiler-specific definitions modernized and moved to compiler.h. | |

| 61 | |
| 62 "Mule-izing" is the process of going through a file and eliminating | |
| 63 assumptions that the internal format (Ibyte * text) is the same as the | |
| 64 external format used by library routines. Mule-ization should also | |
| 65 include replacing *ALL* raw references to `char' or `unsigned char' with | |
| 66 one of the self-documenting types created below. How exactly to do the | |
| 67 conversion, and how to write correctly Mule-ized code, is described in | |
| 68 the internals manual. Files that say "This file is Mule-ized" have | |
| 69 been reviewed at some point; that's not to say that incorrect code hasn't | |
| 70 crept in, though. | |
| 71 | |
| 72 "Unicode-splitting" is the process of fixing a file so that it will | |
| 73 handle external text in Unicode under Microsoft Windows, as appropriate. | |
| 74 ("splitting" because it needs to handle either Unicode or variable-width | |
| 75 multibyte depending on the OS -- NT or 9x). See intl-win32.c. | |
| 76 | |
| 77 #### is a way of marking problems of any sort. | |
| 78 | |
| 79 !!#### marks places that are not properly Mule-ized. | |
| 80 | |
| 81 &&#### marks places that need to be fixed in order for the "8-bit mule" | |
| 82 conversion to work correctly, i.e. in order to support multiple different | |
| 83 buffer formats under Mule, including a fixed 8-bit format. | |
| 84 | |
| 85 ^^#### marks places that need to be fixed in order to eliminate the | |
| 86 assumption that Ibyte * text is composed of 1-byte units (e.g. UTF-16 | |
| 87 is composed of 2-byte units and might be a possible format to consider | |
| 88 for Ibyte * text). | |

| 288 attribute specific meaning to types that by themselves are pretty | |
| 289 general. | |
| 290 | |
| 291 REMEMBER! These typedefs are purely for documentation purposes; from | |
| 647 | 292 the C code's perspective, they are exactly equivalent to `char *', |
| 293 `unsigned char *', etc., so you can freely use them with library | |
| 2367 | 294 functions declared as such. |
| 295 | |
| 296 (See also "Byte/Character Types" in text.c) | |
| 297 | |
| 298 The basic semantics for `char': | |
| 299 | |
| 300 a) [Ibyte] pointer to internally-formatted text | |
| 301 b) [Extbyte] pointer to text in some external format, which can be | |
| 302 defined as all formats other than the internal one | |
| 303 c) [Ascbyte] pure ASCII text | |
| 304 d) [Binbyte] binary data that is not meant to be interpreted as text | |
| 305 e) [Rawbyte] general data in memory, where we don't care about whether | |
| 306 it's text or binary | |
| 307 f) [Boolbyte] a zero or a one | |
| 308 g) [Bitbyte] a byte used for bit fields | |
| 309 h) [Chbyte] null-semantics `char *'; used when casting an argument to | |
| 310 an external API where the the other types may not be | |
| 311 appropriate | |
| 312 | |
| 313 | |
| 314 Prefixing codes: | |
| 315 | |
| 316 C = plain char, when the base type is unsigned | |
| 317 U = unsigned | |
| 318 S = signed | |
| 319 | |
| 320 Ideally, XEmacs code should NEVER directly use `char' or any type | |
| 321 derived from it. This is for Mule-cleanliness. If you find yourself | |
| 322 wanting or needing to use `char' and one of the above six semantics does | |
| 323 not apply, add a new type of semantics; don't use `char' directly. | |

| 851 | 1096 We provide MALLOC_OR_ALLOCA() below for places where it's likely that |
| 1097 large amounts will be allocated; it mallocs the block if it's too big. | |
| 1098 Unfortunately, that requires a call to unbind_to() at the end of the | |
| 1099 function, and it's not feasible to rewrite all calls to alloca() this | |
| 1100 way. | |
| 1101 | |
| 1102 Instead, we use the portable C alloca() substitute in alloca.c above a | |
| 1103 certain size. This actually uses malloc(), but checks the current stack | |
| 1104 pointer to see if data from previous alloca() calls needs to be freed. | |
| 1105 However, this can lead to large heap sizes -- especially since cleanup | |
| 1106 can only happen in a parent function, and will never happen if (as will | |
| 1107 often be the case) it's the same function in the same place in the code | |
| 1108 that keeps tripping the alloca() limit. | |
| 1109 | |
| 1110 So we set up a system to periodically force cleanup. Currently we | |
| 1111 do cleanup: | |
| 1112 | |
| 1113 -- Only when there's C alloca() data, and then | |
| 1114 -- Every stack alloca() or allocation of Lisp data, every call to | |
| 1115 next_event_internal() [typically near the top of the stack], | |
| 1116 or every 10th funcall | |
| 1117 | |
| 1118 This should not be a big penalty because | |
| 1119 | |
| 1120 (a) If there are few C alloca() chunks, checking them will be fast | |
| 1121 (b) If not, we've allocated a huge amount of heap space (remember, each | |

| 1882 and executing code that you specify on each member of the list. | |
| 1883 | |
| 1884 There are two kinds of macros, those requiring surrounding braces, and | |
| 1885 those not requiring this. Which type of macro will be indicated. | |
| 1886 The general format for using a brace-requiring macro is | |
| 1887 | |
| 1888 { | |
| 1889 LIST_LOOP_3 (elt, list, tail) | |
| 1890 execute_code_here; | |
| 1891 } | |

| 1893 or | |
| 1894 | |
| 1895 { | |
| 1896 LIST_LOOP_3 (elt, list, tail) | |
| 1897 { | |
| 1898 execute_code_here; | |
| 1899 } | |
| 1900 } | |
| 1901 | |
| 1902 You can put variable declarations between the brace and beginning of | |
| 1903 macro, but NOTHING ELSE. | |
| 1904 | |
| 1905 The brace-requiring macros typically declare themselves any arguments | |
| 1906 that are initialized and iterated by the macros. If for some reason | |
| 1907 you need to declare these arguments yourself (e.g. to do something on | |
| 1908 them before the iteration starts, use the _NO_DECLARE versions of the | |
| 1909 macros.) | |
| 1910 */ | |
| 1911 | |
| 1912 /* There are two basic kinds of macros: those that handle "internal" lists | |
| 1913 that are known to be correctly structured (i.e. first element is a cons | |
| 1914 or nil, and the car of each cons is also a cons or nil, and there are | |
| 1915 no circularities), and those that handle "external" lists, where the | |
| 1916 list may have any sort of invalid formation. This is reflected in | |
| 1917 the names: those with "EXTERNAL_" work with external lists, and those | |
| 1918 without this prefix work with internal lists. The internal-list | |
| 1919 macros will hit an assertion failure if the structure is ill-formed; | |
| 1920 the external-list macros will signal an error in this case, either a | |
| 1921 malformed-list error or a circular-list error. | |
| 1922 */ | |

| 1927 to each cons starting with the first), and LIST, the list to iterate | |
| 1928 over. TAIL needs to be defined by the caller. | |
| 442 | 1929 |
| 1930 In each iteration, you can retrieve the current list item using XCAR | |

| 1942 | |
| 1943 LIST_LOOP_2 and EXTERNAL_LIST_LOOP_2 are the standard, most-often used | |
| 1944 macros. They take two arguments, an element variable ELT and the list | |

| 1947 | |
| 1948 LIST_LOOP_3 and EXTERNAL_LIST_LOOP_3 are the same, but they have a third | |
| 1949 argument TAIL, another automatically-declared variable. At each iteration, | |
| 1950 this one points to the cons cell for which ELT is the car. | |
| 1951 | |
| 1952 EXTERNAL_LIST_LOOP_4 is like EXTERNAL_LIST_LOOP_3 but takes an additional | |
| 1953 LEN argument, again automatically declared, which counts the number of | |
| 1954 iterations gone by. It is 0 during the first iteration. | |
| 1955 | |

| 3189 as a null-terminated C string. | |
| 3190 `Fname' should be the C equivalent of `lname', using only characters | |
| 3191 valid in a C identifier, with an "F" prepended. | |
| 3192 The name of the C constant structure that records information | |

| 3195 `max_args' should be a number, the maximum number of arguments allowed, | |
| 3196 or else MANY or UNEVALLED. | |
| 3197 MANY means pass a vector of evaluated arguments, | |
| 3198 in the form of an integer number-of-arguments | |
| 3199 followed by the address of a vector of Lisp_Objects | |
| 3200 which contains the argument values. | |
| 3201 UNEVALLED means pass the list of unevaluated arguments. | |
| 3202 `prompt' says how to read arguments for an interactive call. | |
| 3203 See the doc string for `interactive'. | |
| 3204 A null string means call interactively with no arguments. | |
| 3205 `arglist' are the comma-separated arguments (always Lisp_Objects) for | |
| 3206 the function. | |
| 3207 The docstring for the function is placed as a "C" comment between | |
| 3208 the prompt and the `args' argument. make-docfile reads the | |
| 3209 comment and creates the DOC file from it. | |
