KDK_CPU_GET_PROCESS(3) Library Functions Manual KDK_CPU_GET_PROCESS(3)

kdk_cpu_get_process - 获取CPU线程数

#include <libkycpu.h>

extern unsigned int kdk_cpu_get_process()

Link with -lkyhw.

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

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

On error, return 0.

#include "libkycpu.h"
#include <stdio.h>
int main()
{
    printf("架构:%s\n", kdk_cpu_get_arch());
    printf("生产厂商:%s\n", kdk_cpu_get_vendor());
    printf("CPU 型号:%s\n", kdk_cpu_get_model());
    printf("CPU 主频:%s MHz\n", kdk_cpu_get_freq_MHz());
    printf("CPU 单核核心数量:%u\n", kdk_cpu_get_corenums());
    printf("CPU 虚拟化支持:%s\n", kdk_cpu_get_virt());
    printf("CPU 线程数:%u\n", kdk_cpu_get_process());
    return 0;
}

These functions are as per the withdrawn POSIX.1e draft specification. The following functions are Linux extensions: kdk_cpu_get_vendor(), kdk_cpu_get_model(), kdk_cpu_get_freq_MHz(), kdk_cpu_get_arch(), kdk_cpu_get_virt() and kdk_cpu_get_corenums().

kdk_cpu_get_vendor(3), kdk_cpu_get_model(3), kdk_cpu_get_freq_MHz(3), kdk_cpu_get_arch(3), kdk_cpu_get_virt(3) and kdk_cpu_get_corenums(3).
