mkstemp

Syntax

#include <stdio.h> int mkstemp(char *template);

Description

template is a file specification that ends with six trailing X characters. This function replaces the XXXXXX with a set of characters such that the resulting file name names a nonexisting file. It then creates and opens the file in a way which guarantees that no other process can access this file.

Note that since MS-DOS is limited to eight characters for the file name, and since none of the X's get replaced by a dot, you can only have two additional characters before the X's.

Note also that the path you give will be modified in place.

Return Value

The open file descriptor.

Portability

ANSI/ISO C	No
POSIX	No

Example

char path[100]; strcpy(path, "/tmp/ccXXXXXX"); int fd = mkstemp(path);
