Syntax

#include <process.h>
int getpid(void);

getpid gets the process identifier that uniquely identifies the calling process.

Note: In earlier releases of C Set ++, getpid began with an underscore (_getpid). Because it is defined by the X/Open standard, the underscore has been removed. For compatibility, The Developer's Toolkit will map _getpid to getpid for you.

getpid function the process identifier as an integer value. There is no error return value.

This example prints the process identifier:

#include <process.h>
#include <string.h>
#include <stdio.h>
#include <stdlib.h>

int main(void)
{
   printf("Process identifier is %05d\n", getpid());
   return 0;

   /****************************************************************************
      The output should be similar to:

      Process identifier is 00242
   ****************************************************************************/
}
