Name
zmq_strerror - 获取ZMQ错误描述字符串
Synopsis
const char *zmq_strerror (int errnum);
Description
zmq_strerror()函数会返回errnum参数对应的错误描述字符串的指针。由于ZMQ在操作系统之上增加了错误定义,应用程序更应该倾向于使用zmq_strerror() 函数而不是标准函数strerror() 。
Return value
zmq_strerror()函数返错误描述字符串的指针。
Errors
没有定义错误代码。
Example
显示一个ZMQ context无法被初始化的错误信息
void *ctx = zmq_init (1, 1, 0);
if (!ctx) {
printf ("Error occurred during zmq_init(): %s\n", zmq_strerror (errno));
abort ();
}
