| Linux / Unix Command: tmpnam |
NAME
tmpnam - create a name for a temporary fileSYNOPSIS
#include <stdio.h> char *tmpnam(char *s);
DESCRIPTION
The tmpnam() function returns a pointer to a string that is a valid filename, and such that a file with this name did not exist at some point in time, so that naive programmers may think it a suitable name for a temporary file. If the argument s is NULL this name is generated in an internal static buffer and may be overwritten by the next call to tmpnam(). If s is not NULL, the name is copied to the character array (of length at least L_tmpnam) pointed at by s and the value s is returned in case of success.The path name that is created, has a directory prefix P_tmpdir. (Both L_tmpnam and P_tmpdir are defined in <stdio.h>, just like the TMP_MAX mentioned below.)
RETURN VALUE
The tmpnam() function returns a pointer to a unique temporary filename, or NULL if a unique name cannot be generated.ERRORS
No errors are defined.SEE ALSO
