69 /* Emacs needs to use its own definitions of certain system calls on
|
|
|
70 some systems (like SunOS 4.1 and USG systems, where the read system
|
|
|
71 call is interruptible but Emacs expects it not to be; and under
|
|
|
72 MULE, where all filenames need to be converted to external format).
|
|
|
73 To do this, we #define read to be sys_read, which is defined in
|
|
|
74 sysdep.c. We first #undef read, in case some system file defines
|
|
|
75 read as a macro. sysdep.c doesn't encapsulate read, so the call to
|
|
|
76 read inside of sys_read will do the right thing.
|
|
|
77
|
|
|
78 DONT_ENCAPSULATE is used in files such as sysdep.c that want to
|
|
|
79 call the actual system calls rather than the encapsulated versions.
|
|
|
80 Those files can call sys_read to get the (possibly) encapsulated
|
|
|
81 versions.
|
|
|
82
|
|
|
83 IMPORTANT: the redefinition of the system call must occur *after* the
|
|
|
84 inclusion of any header files that declare or define the system call;
|
|
|
85 otherwise lots of unfriendly things can happen. This goes for all
|
|
|
86 encapsulated system calls.
|
|
|
87
|
|
|
88 We encapsulate the most common system calls here; we assume their
|
|
|
89 declarations are in one of the standard header files included above.
|
|
|
90 Other encapsulations are declared in the appropriate sys*.h file. */

302 /* Entomological studies have revealed that the following junk is
|
|
|
303 necessary under GCC. GCC has a compiler bug where incorrect
|
|
|
304 code will be generated if you use a global temporary variable
|
|
|
305 in a macro and the macro occurs twice in the same expression.
|
|
|
306 As it happens, we can avoid this problem using a GCC language
|
|
|
307 extension. Thus we play weird games with syntax to avoid having
|
|
|
308 to provide two definitions for lots of macros.
|
|
|
309
|
|
|
310 The approximate way this works is as follows:
|
|
|
311
|
|
|
312 1. Use these macros whenever you want to avoid evaluating an
|
|
|
313 argument more than once in a macro. (It's almost always a
|
|
|
314 good idea to make your macros safe like this.)
|
|
|
315 2. Choose a name for the temporary variable you will store
|
|
|
316 the parameter in. It should begin with `MT' and
|
|
|
317 be distinguishing, since it will (or may) be a global
|
|
|
318 variable.
|
|
|
319 3. In the same header file as the macro, put in a
|
|
|
320 MAC_DECLARE_EXTERN for the temporary variable. This
|
|
|
321 resolves to an external variable declaration for some
|
|
|
322 compilers.
|
|
|
323 4. Put a MAC_DEFINE for the variable in a C file somewhere.
|
|
|
324 This resolves to a variable definition for some compilers.
|
|
|
325 5. Write your macro with no semicolons or commas in it.
|
|
|
326 Remember to use parentheses to surround macro arguments,
|
|
|
327 but you do not need to surround each separate statement
|
|
|
328 or the temporary variable with parentheses.
|
|
|
329 6. Write your macro like this:
|
|
|
330
|
|
|
331 #define foo(bar,baz) \
|
|
|
332 MAC_BEGIN \
|
|
|
333 MAC_DECLARE (struct frobozz *, MTfoobar, bar) \
|
|
|
334 SOME_EXPRESSION \
|
|
|
335 MAC_SEP \
|
|
|
336 SOME OTHER EXPRESSION \
|
|
|
337 MAC_END
|
|
|
338
|
|
|
339 7. You only need to use MAC_SEP if you have more than one
|
|
|
340 expression in the macro, not counting any MAC_DECLARE
|
|
|
341 statements.
|
|
|
342
|
|
|
343 DONT_DECLARE_MAC_VARS is used in signal.c, for asynchronous signals.
|
|
|
344 All functions that may be called from within an asynchronous signal
|
