KDK_GET_PROCESS_ID(3)      Library Functions Manual      KDK_GET_PROCESS_ID(3)

NAME
       kdk_get_process_id - <?><?><?><?><?><?><?>id

SYNOPSIS
       #include <libkyprocess.h>

       extern int kdk_get_process_id(char *proc_name);

       Link with -lkyrtinfo.

Detailed Description
       The main function of the interface is to obtain the PID of the
       specified process.

       The argument proc_num is the name of the process.

RETURN VALUE
       On success, returns the PID of the process of type int.

       On error, return 0.

       #include "libkyprocess.h"
       #include <stdio.h>
