NAME
     tt_message_xcontext_set - set the XDR-interpreted byte-array value of a
     message's context

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

DESCRIPTION
     The tt_message_xcontext_set() function sets the XDR-interpreted byte-
     array value of a message's context.

     The m argument is the opaque handle for the message involved in this
     operation.  The slotname argument describes the slotname in this message.
     The value argument is the byte string with the contents for the message
     argument.  The xdr_proc argument points to the XDR procedure to be used
     to serialize the data pointed to by value.  The value argument is the
     data to be serialized.

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

        TT_OK   The operation completed successfully.

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

        TT_ERR_POINTER
                The pointer does not point at an object of the correct type
                for this operation.

        TT_ERR_SLOTNAME
                The specified slotname is syntactically invalid.

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