t_close(3N)

NAME
     t_close - close a transport endpoint

SYNOPSIS
     #ifdef _XOPEN_SOURCE
     #include <xti.h>
     #else
     #include <tiuser.h>
     #endif

     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.

     This function resides within both the X/Open compliant libxnet and the
     SVR4 compliant libnsl Network Services libraries.  Network Services
     applications which require X/Open compliance must link-load with -lxnet.
     Network Services applications which require SVR4 compliance must link-
     load with -lnsl.

     On failure, t_errno may be set to the following:

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

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