以下是pthread_setname_np的函数原型: `int pthread_setname_np(pthread_t thread, const char *name);` thread参数是线程ID,由创建线程的调用返回。name参数是指向要分配的名字的指针。 如果成功,pthread_setname_np函数返回零。否则,它返回错误代码。 异常情况 如果线程名太长或缓冲区太小,则会发生以下异常情...
检查平台支持:确认你的平台支持 pthread_setname_np 函数。如果不支持,你可能需要寻找其他设置线程名称的方法。 调整编译器选项:确保编译器选项没有禁用对 pthread_setname_np 的支持。例如,避免定义 _POSIX_C_SOURCE 为一个较低的版本,这可能会隐藏某些非标准的函数声明。 下面是一个示例代码片段,展示了如何在包...
多线程与同步:如果在创建线程后立即调用pthread_setname_np(),请确保没有其他操作(比如大量计算或阻塞操作)导致输出被延迟。有时在复杂程序中,多线程运行会造成不一致性,可以通过适当的调试或日志记录来验证实际情况。 检查返回值:你可以检查pthread_setname_np()的返回值,以确定是否成功设置了线程名称。例如: intr...

implicit declaration of function ‘pthread_setname_np’ Apparently we need to set: #define _GNU_SOURCE before we #include <pthread.h> Not sure how portable that is. We could also revert it.
pthread_setname_np is implemented in glibc with two different code paths. When called on a target thread other than the current thread, it attempts to write to /proc/self/task/<taskid>/comm. However, when a process calls setuid/seteuid, the proc entries underneath remain owned by the pr...
确定您的平台是否支持pthread_setname_np()函数。可以查阅您的平台的相关文档或者操作系统的手册来确认。如果支持,可以继续下一步;如果不支持,那么pthread_setname_np()函数将无法使用。 编写一个简单的测试程序,调用pthread_setname_np()函数并设置线程的名称。例如,以下是一个示例程序: ...
