861 @defun user-home-directory
862 This function returns the ``@code{HOME}'' directory of the user, and is
863 intended to replace occurrences of ``@code{(getenv "HOME")}''. Under
864 Unix systems, the following is done:
865
866 @enumerate
867 @item
868 Return the value of ``@code{(getenv "HOME")}'', if set.
869
870 @item
871 Return ``/'', as a fallback, but issue a warning. (Future versions of
872 XEmacs will also attempt to lookup the @code{HOME} directory via
873 @code{getpwent()}, but this has not yet been implemented.)
874 @end enumerate
875
876 Under MS Windows, this is done:
877
878 @enumerate
879 @item
880 Return the value of ``@code{(getenv "HOME")}'', if set.
881
882 @item
883 If the environment variables @code{HOMEDRIVE} and @code{HOMEDIR} are
884 both set, return the concatenation (the following description uses MS
885 Windows environment variable substitution syntax):
886 @code{%HOMEDRIVE%%HOMEDIR%}.
887
888 @item
889 Return ``C:\'', as a fallback, but issue a warning.
