Remarks

tmpfile creates a temporary binary file and opens it for update {w + b). The file is automatically removed when it's closed or when your program terminates.

tmpfile creates the temporary file in the directory defined by the TMP environment variable. If TMP is not defined, the TEMP environment variable is used. If neither TMP or TEMP is defined, tmpfile creates the files in the current directory.

Return value

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

   if (tempfp)

else {
   printf("Unable to create  temporary file\n");
   exit(l);
}
return 0;
