ttdt_Save(3)

NAME
     ttdt_Save - request a ToolTalk client to save a file

SYNOPSIS
     #include <Tt/tttk.h>
     Tt_status ttdt_Save(Tt_message context,
                         const char *pathname,
                         Tt_scope the_scope,
                         XtAppContext app2run,
                         int ms_timeout);

DESCRIPTION
     The ttdt_Save() function sends a Save request in the the_scope argument
     and waits for the reply.  A Save request asks the handling ToolTalk
     client to save any changes pending on pathname.

     The context argument describes the environment to use.  If context is not
     zero, messages created by ttdt_Save() inherit from context all contexts
     whose slotname begins with the characters ENV_.

     The the_scope argument identifies the scope of the request.  If the_scope
     is TT_SCOPE_NONE, ttdt_Save() tries TT_BOTH, and falls back to
     TT_FILE_IN_SESSION if, for example, the ToolTalk database server is not
     installed on the file server that owns pathname.

     The ttdt_Save() function passes app2run and ms_timeout to
     tttk_block_while(3), blocking on the reply to the Save request it sends.

RETURN VALUE
     Upon successful completion, the ttdt_Save() function returns the status
     of the operation as one of the following Tt_status values:

        TT_OK   The sent request received an affirmative reply within
                ms_timeout milliseconds.

        TT_DESKTOP_ETIMEDOUT
                No reply was received within ms_timeout milliseconds.

        TT_DESKTOP_EPROTO
                The request was failed, but the handler set the
                tt_message_status() of the failure reply to TT_OK, instead of
                a specific error status.

        TT_ERR_DBAVAIL
                The ToolTalk service could not access the ToolTalk database
                needed for this operation.

        TT_ERR_DBEXIST
                The ToolTalk service could not access the specified ToolTalk
                database in the expected place.
        TT_ERR_NOMEM
                There is insufficient memory available to perform the
                function.

        TT_ERR_NOMP
                The ttsession(1) process is not running and the ToolTalk
                service cannot restart it.

        TT_ERR_OVERFLOW
                The ToolTalk service has more active messages than it can
                handle.  (The maximum number of active messages is
                implementation specific, but is at least 2000.)

        TT_ERR_POINTER
                The pathname argument was NULL or was a ToolTalk error
                pointer.

        TT_ERR_PROCID
                The specified process identifier is out of date or invalid.
