After a successful <<rename>>, the file is no longer accessible by the string at <[old]>. If <<rename>> fails, the file named <<*<[old]>>> is unaffected. The conditions for failure depend on the host operating system. RETURNS The result is either <<0>> (when successful) or <<-1>> (when the file could not be renamed). PORTABILITY ANSI C requires <<rename>>, but only specifies that the result on failure be nonzero. The effects of using the name of an existing file as <<*<[new]>>> may vary from one implementation to another. Supporting OS subroutines required: <<link>>, <<unlink>>, or <<rename>>. */ #include <_ansi.h> #include <reent.h> #include <stdio.h> #include <sys/unistd.h> #ifndef _REENT_ONLY int _DEFUN(rename, (old, new), _CONST char *old _AND _CONST char *new) { return _rename_r (_REENT, old, new); } #endif
