NAME

kdk_cpu_get_corenums - 获取CPU核心数量

SYNOPSIS

#include <libkycpu.h>

extern unsigned int kdk_cpu_get_corenums()

Link with -lkyhw.

Detailed Description

The main function of the interface is to obtain the number of CPU cores

RETURN VALUE

On success, returns the number of all available CPU cores of type int.

On error, return 0.
