读取AMD笔记本的CPU温度的C++代码

以下是读取AMD笔记本的CPU温度的C代码：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>

#define MAX_LINE_LENGTH 1024

int main()
{
    FILE* fp;
    char line[MAX_LINE_LENGTH];
    char* token;
    const char* delimiter = " ";
    const char* search_str = "Tdie";
    float temperature = 0;

    fp = fopen("/sys/class/hwmon/hwmon0/temp1_input", "r");
    if (fp == NULL) {
        fprintf(stderr, "Failed to open file\n");
        exit(EXIT_FAILURE);
    }

    while (fgets(line, MAX_LINE_LENGTH, fp) != NULL) {
        token = strtok(line, delimiter);
        if (strcmp(token, search_str) == 0) {
            token = strtok(NULL, delimiter);
            temperature = strtof(token, NULL) / 1000;
            break;
        }
    }

    printf("CPU temperature is %.2f degrees Celsius\n", temperature);

    fclose(fp);
    return 0;
}

这段代码打开`/sys/class/hwmon/hwmon0/temp1_input`文件，该文件包含了AMD笔记本的CPU温度信息。然后，它逐行读取该文件并查找包含“Tdie”字符串的行。一旦找到该行，它会解析出温度值并将其打印出来。最后，它关闭文件并退出。
