As stated that __func__ is a predefined identifier which stores the name of the function currently being executed. These are defined and implemented by C language as Predefined Macro Names. There is no need for any header file include directive. Please note that there are other predefined identifier like __DATE__ , __TIME__ ,__FILE__ etc that the language implements.

Regarding function signatures you might have to change the function signatures in case if you are not able to find an efficient alternative.

Hope this helps.

tt_ptype_opnum_callback_add(library call)								 tt_ptype_opnum_callback_add(library call)

NAME
tt_ptype_opnum_callback_add -- return a callback if two opnums are equal SYNOPSIS
#include <Tt/tt_c.h> Tt_status tt_ptype_opnum_callback_add( const char *ptid, int opnum, Tt_message_callback f); DESCRIPTION
The tt_ptype_opnum_callback_add function returns a callback if the specified opnums are equal. The callback is defined in Tt/tt_c.h - Tttt_c(5). When a message is delivered because it matched a pattern derived from a signature in the named ptype with an opnum equal to the specified one, the given callback is run in the usual ToolTalk way. The ptid argument is the identifier of the ptype involved in this operation. The opnum argument is the opnum of the specified ptype. The f argument is the message callback to be run. RETURN VALUE
Upon successful completion, the tt_ptype_opnum_callback_add function returns the status of the operation as one of the following Tt_status values: TT_OK The operation completed successfully. TT_ERR_PTYPE The specified process type is not the name of an installed process type. TT_ERR_POINTER The pointer passed does not point to an object of the correct type for this operation. TT_ERR_NOMP The ttsession(1) process is not running and the ToolTalk service cannot restart it. APPLICATION USAGE
The tt_ptype_opnum_callback_add function will only be called for messages delivered by virtue of matching handler signatures. The callback cannot be called for observer signatures because the observer ptype is not recorded in the incoming message. SEE ALSO
Tt/tt_c.h - Tttt_c(5). tt_ptype_opnum_callback_add(library call)
