char *tmpnam(char *s); The tmpnam() function generates a unique temporary filename using the path prefix P_tmpdir defined in <stdio.h>. If the argument s is NULL, tmpnam() returns the address of an internal static area which holds the filename, which is overwritten by subsequent calls to tmpnam(). If s is not NULL, the filename is returned in s. The tmpnam() function returns a pointer to the unique temporary filename, or NULL if a unique name cannot be generated. - EEXIST
