我的程序创建socket出错，根据api设置的errno值（一个全局的值吧？），但是不知道相应的具体含义是什么？请问到哪个文件里去看这些信息? 请提供一些这些方面的信息！

#ifndef _I386_errno_H #define _I386_errno_H 　　 #define EPERM 1 /* Operation not permitted */ #define ENOENT 2 /* No such file or directory */ #define ESRCH 3 /* No such process */ #define EINTR 4 /* Interrupted system call */ #define EIO 5 /* I/O error */ #define ENXIO 6 /* No such device or addres...

DESCRIPTION The <errno.h> header file defines the integer variable errno, which is set by system calls and some library functions in the event of an error to indicate what went wrong. Its value is significant only when the call returned an error (usu鈥[m ally -1), and a function that does succeed is allowed to change errno. Sometimes, when -1 is also a valid succe...

在多线程里怎么出理errno. 比如: if (write(fd, buf,...) <0 ){ perror("write failed"); if(errno == EINTR){......} } 这样的代码在多线成里肯定不行,怎么处理好呢?

在APUE中，有这样的例子[code]#include #include #include #include <errno.h> int initserver(int type, const struct sockaddr *addr, socklen_t alen, int qlen) { int fd; int err = 0; if((fd = socket(addr->sa_family, type, 0)) < 0) return -1; if(bind(fd, addr, alen) < 0) { err = errno; goto errout; } if(type == SOCK_STREAM || type == SOCK_SEQPACKET) { i...
