C <stdio.h> - TMP_MAX constant

The C <stdio.h> TMP_MAX is a macro constant that expands to maximum number of unique temporary file names that are guaranteed to be possible to generate using tmpnam() function.

In the <stdio.h> header file, it is defined as follows:

#define TMP_MAX /* implementation defined */

Example:

The example below shows the value of TMP_MAX constant on a given implementation.

#include <stdio.h>
 
int main (){
  //displaying the value of TMP_MAX
  printf("TMP_MAX = %d\n", TMP_MAX);
 
  return 0;
}

One of the possible output of the above code could be:

TMP_MAX = 238328
