header file: unistd.h

pid_t getpid(void);

header file: process.h

int _getpid(void);

This function returns the process ID of the calling process.

Since this function has a direct analog in Windows, the only changes that should be needed are to rename the function in your source code, and include the needed Windows header file.

#include <process.h>

  printf("The process ID is %d.", _getpid());
