Defined in header <stdio.h>
int rename( const char *old_filename, const char *new_filename );

Changes the filename of a file. The file is identified by character string pointed to by old_filename. The new filename is identified by character string pointed to by new_filename.

If new_filename exists, the behavior is implementation-defined.

Parameters

old_filename	-	pointer to a null-terminated string containing the path identifying the file to rename
new_filename	-	pointer to a null-terminated string containing the new path of the file

Return value

​0​ upon success or non-zero value on error.

Notes

POSIX specifies many additional details on the semantics of this function.
