NAME

t_close − close a transport endpoint

SYNOPSIS

#include <tiuser.h>

int t_close(fd)
int fd;

DESCRIPTION

The t_close function informs the transport provider that the user is finished with the transport endpoint specified by fd, and frees any local library resources associated with the endpoint.  In addition, t_close closes the file associated with the transport endpoint. 

t_close should be called from the T_UNBND state [see t_getstate(3N)].  However, this function does not check state information, so it may be called from any state to close a transport endpoint.  If this occurs, the local library resources associated with the endpoint will be freed automatically.  In addition, close(2) will be issued for that file descriptor; the close will be abortive if no other process has that file open, and will break any transport connection that may be associated with that endpoint. 

On failure, t_errno may be set to the following:

TBADF The specified file descriptor does not refer to a transport endpoint. 

SEE ALSO

t_getstate(3N), t_open(3N), t_unbind(3N). 

DIAGNOSTICS

t_close returns 0 on success and −1 on failure and t_errno is set to indicate the error.
