@deftypefn Supplemental char* tmpnam (char *@var{s})
|
|
|
|
This function attempts to create a name for a temporary file, which
|
|
will be a valid file name yet not exist when @code{tmpnam} checks for
|
|
it. @var{s} must point to a buffer of at least @code{L_tmpnam} bytes,
|
|
or be @code{NULL}. Use of this function creates a security risk, and it must
|
|
not be used in new projects. Use @code{mkstemp} instead.
