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;
}
