KDK_GET_PROCESS_START_TIME(3)

NAME
kdk_get_process_start_time - 获取某一进程的启动时间

SYNOPSIS
#include <libkyprocess.h>

extern char* kdk_get_process_start_time(int proc_num);

Link with -lkyrtinfo.

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

The argument proc_num is the PID of the process.

RETURN VALUE
On success, returns the start time of the process of type char*, such as "Mon Sep 18 08:40:37 2023"; The returned string needs to be released by free

On error, return NULL.
