gdb打印errno显示cant find thread-local storage xxxx

errno即最后一次错误的错误码，定义在<errno.h>里面，是一个宏

#if !defined _LIBC || defined _LIBC_REENTRANT
/* When using threads,errno is a per-thread value. */
#define errno (*__errno_location ())
# endif

errno是线程安全的，好像每个线程都有自己的errno
打印errno是一个错误码，还需要去对照找具体含义，而调用一下下面这个函数就可以将错误码转换成字符串描述的错误信息

char *strerror(int errno)

当在gdb里打印errno值的时候，有可能会出现cant find thread-local storage xxxx的提示信息，这时可以尝试直接打印p *__errno_location (),需要注意的是注意函数原型有没有问题，ptype看下，万一是64位cpu可能有数据被截断的风险
