NAME

shutdown − shut down part of a full-duplex connection

SYNOPSIS

shutdown(s, how)
int s, how;

DESCRIPTION

The shutdown call causes all or part of a full-duplex connection on the socket associated with s to be shut down.  If how is 0, then further receives are disallowed.  If how is 1, then further sends are disallowed.  If how is 2, then further sends and receives are disallowed. 

DIAGNOSTICS

A 0 is returned if the call succeeds, −1 if it fails. 

ERRORS

The call succeeds unless:

[EBADF] s is not a valid descriptor. 

[ENOTSOCK] s is a file, not a socket. 

[ENOTCONN] The specified socket is not connected.
