MKTEMP(3-SysV)      RISC/os Reference Manual       MKTEMP(3-SysV)



NAME
     mktemp - make a unique file name

SYNOPSIS
     char *mktemp (template)
     char *template;

DESCRIPTION
     mktemp replaces the contents of the string pointed to by
     template by a unique file name, and returns the address of
     template.  The string in template should look like a file
     name with six trailing Xs; mktemp will replace the Xs with a
     letter and the current process ID.  The letter will be
     chosen so that the resulting name does not duplicate an
     existing file.

SEE ALSO
     getpid(2), tmpfile(3S), tmpnam(3S).

DIAGNOSTIC
     mktemp will assign to template the NULL string if it cannot
     create a unique name.

CAVEAT
     If called more than 17,576 time in a single process, this
     function will start recycling previously used names.
