C++ (Cpp) GetCpuCountFromString示例

示例#1

文件： sysinfo.cpp 项目： android/platform_bionic

int get_nprocs() {
  int cpu_count = 1;
  FILE* fp = fopen("/sys/devices/system/cpu/online", "re");
  if (fp != nullptr) {
    char* line = nullptr;
    size_t len = 0;
    if (getline(&line, &len, fp) != -1) {
      cpu_count = GetCpuCountFromString(line);
      free(line);
    }
    fclose(fp);
  }
  return cpu_count;
}
