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

}
