Function Documentation

int explain_getsockname_on_error ( int  fildes,
struct sockaddr *  sock_addr,
socklen_t *  sock_addr_size 
)

The explain_getsockname_on_error function is used to call the getsockname(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_getsockname(3) function.

This function is intended to be used in a fashion similar to the following example:

 if (explain_getsockname_on_error(fildes, sock_addr, sock_addr_size) < 0)
 {
     ...cope with error
     ...no need to print error message
 }
Parameters:
fildesThe fildes, exactly as to be passed to the getsockname(2) system call.
sock_addrThe sock_addr, exactly as to be passed to the getsockname(2) system call.
sock_addr_sizeThe sock_addr_size, exactly as to be passed to the getsockname(2) system call.
Returns:
The value returned by the wrapped getsockname(2) system call.
