#include <stdio.h> int _rename(const char *oldname, const char *newname);
This function renames an existing file or directory oldname to
newname. It is much smaller that
rename (see section rename),
but it can only rename a directory so it stays under the same parent, it
cannot move directories between different branches of the directory
tree. This means that in the following example, the first call will
succeed, while the second will fail:
_rename("c:/path1/mydir", "c:/path1/yourdir"); _rename("c:/path1/mydir", "c:/path2");
On systems that support long filenames (see section _use_lfn),
_rename can also move directories (so that both calls in the
above example succeed there), unless the `LFN' environment variable
is set to n, or the
_CRT0_FLAG_NO_LFN is set in the
_crt0_startup_flags variable, See section _crt0_startup_flags.
If you don't need the extra functionality offered by
(which usually is only expected by Unix-born programs), you can use
_rename instead and thus make your program a lot smaller.
Zero on success, nonzero on failure.
