Header File

Category

Input/output Routines

Prototype

FILE *tmpfile(void);

Description

Opens a “scratch” file in binary mode.

tmpfile creates a temporary binary file and opens it for update (w + b). If you do not change the directory after creating the temporary file, the file is automatically removed when it’s closed or when your program terminates.

Return Value

tmpfile returns a pointer to the stream of the temporary file created. If the file can’t be created, tmpfile returns NULL.

Example

 #include <stdio.h>
 #include <process.h>
 int main(void)
 {
    FILE *tempfp;
    tempfp = tmpfile();
    if (tempfp)
       printf("Temporary file created\n");
    else
    {
       printf("Unable to create temporary file\n");
       exit(1);
    }
    return 0;
 }
