#include <Tt/tt_c.h>
char *tt_message_context_val(
Tt_message m,
const char *slotname);
DESCRIPTION
The tt_message_context_val function retrieves the character string of 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 mes-
sage.
If there is no context slot associated with slotname, tt_message_context_val returns a NULL pointer.

tt_ptr_error(3) to extract one of the following Tt_status values from the returned pointer:
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 passed does not point to an object of the correct type for this operation.
TT_ERR_SLOTNAME
The specified slotname is syntactically invalid.
APPLICATION USAGE
