MKTEMP(2)
NAME
mktemp − make a unique file name
SYNOPSIS
char∗ mktemp(char ∗template)
DESCRIPTION
Mktemp replaces template by a unique file name, and returns the address of the template. The template should look like a file name with eleven trailing Xs. The Xs are replaced by a letter followed by the current process id. Letters from a to z are tried until a name that can be accessed (see access(2)) is generated. If no such name can be generated, mktemp returns "/".
