  NAME

    t_close - Closes a transport endpoint

  LIBRARY

    Transport Layer Interface (TLI) Library (libnsl_s.a)

  SYNOPSIS

    #include <tiuser.h>

    int t_close(
      int fd );

  PARAMETERS

    fd   An integer representing a file descriptor

  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.

    The t_close() function should be called from the T_UNBND state [see
    t_getstate()].  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() 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.

  RETURN VALUES

    The function 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.
