tmpfile
Item Value Header file stdio.h Declaration FILE *tmpfile(void); Function opens a temporary binary file for read/write operations and returns a pointer to the stream. Return returns a null pointer on failure.
The temporary file created by tmpfile() is automatically removed when the file is closed or when the program terminates.
You can open TMP_MAX temporary files (up to the limit set by FOPEN_MAX).
#include <stdio.h>
int main(void){
FILE *temp;
if((temp=tmpfile())==NULL) {
printf("Cannot open temporary work file.\n");
exit(1);
}
}
