T_CLOSE(3N)                          SysV                          T_CLOSE(3N)



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.

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

ERRORS
     On failure, t_errno may be set to the following:

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