这是一个简单的接收全部"功能:
Here's a simple "receive all" function:
int recv_all(int sockfd, void *buf, size_t len, int flags)
{
size_t toread = len;
char *bufptr = (char*) buf;
while (toread > 0)
{
ssize_t rsz = recv(sockfd, bufptr, toread, flags);
if (rsz <= 0)
return rsz; /* Error or other end closed cnnection */
toread -= rsz; /* Read less next time */
bufptr += rsz; /* Next buffer position to read into */
}
return len;
}
