NAME
tt_message_context_ival - retrieve the integer value of a message's
context
SYNOPSIS
#include <Tt/tt_c.h>
Tt_status tt_message_context_ival(Tt_message m,
const char *slotname,
int *value);
DESCRIPTION
The tt_message_context_ival() function retrieves the integer 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 context of this mes-
sage. The value argument points to the location to return the value.
If there is no context slot associated with slotname, tt_message_con-
text_ival() returns a NULL pointer in slotname.

returns the status of the operation as one of the following Tt_status
values:
TT_OK The operation completed successfully.

rect type for this operation.
TT_ERR_SLOTNAME
