 tt_message_context_xval(library call) tt_message_context_xval(library call)

 NAME    [Toc]    [Back]
      tt_message_context_xval - retrieve and deserialize the data from a
      message's context

 SYNOPSIS    [Toc]    [Back]
      #include <Tt/tt_c.h>
      Tt_status tt_message_context_xval(
      Tt_message m,
      const char *slotname,
      xdrproc_t xdr_proc,
      void **value);

 DESCRIPTION    [Toc]    [Back]
      The tt_message_context_xval function retrieves and deserializes the
      data from a message's context.

      The m argument is the opaque handle for the message involved in this
      operation.  The slotname argument describes the context of this
      message.  The xdr_proc argument points to the XDR procedure to be used
      to deserialize the data in the nth argument into newly allocated
      storage, the address of which will be stored in the pointer whose
      address is value.

      The value argument is the data to be deserialized.

 RETURN VALUE    [Toc]    [Back]
      Upon successful completion, the tt_message_context_xval function
      returns the status of the operation as one of the following Tt_status

      TT_OK     The operation completed successfully.

                The specified Tt_mode is invalid.

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

                The pointer passed does not point to an object of the
                correct type for this operation.

                The integer value passed was invalid (out of range).

                The XDR procedure failed on the given data, or evaluated to
                a zero-length expression.

 APPLICATION USAGE    [Toc]    [Back]
      The allocation calls are made by the XDR procedure; therefore, any
      storage allocated is not allocated from the ToolTalk allocation stack.
      The application should use the xdr_free(3) call to free this storage.
