ToolTalk Functions tt_message_context_bval(3) NAME tt_message_context_bval - retrieve the byte-array value and length of a message's context SYNOPSIS #include <Tt/tt_c.h> Tt_status tt_message_context_bval(Tt_message m, const char *slotname, unsigned char **value, int *len); DESCRIPTION The tt_message_context_bval() function retrieves the byte-array value and length of a message's context. If there is no context slot associated with slotname, tt_message_con- text_bval() returns a NULL pointer in slotname and zero in len. 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. The len argument is the length of the value in bytes. RETURN VALUE Upon successful completion, the tt_message_context_bval() 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 passed does not point to an object of the cor- rect type for this operation. TT_ERR_SLOTNAME The specified slotname is syntactically invalid.
