// This file was derived from <SWI-Prolog.h> WUNUSED is changed to
// [[nodiscard]], and added to some functions that don't have WUNUSEd
// (possibly WUNUSED should be added for them in SWI-Prolog.h).

// Commented out lines are because:
// - no return value
// - return value 0 doesn't mean "fail"
// - private
// - has "..." or similar that requires a bit more work.
// In addition, some functions that return a boolean as an "int" have
// been changed to use a C++ "bool" (the template functions PlWrap()
// and PlEx() have been written to handle this situations).

// This file is included by SWI-cpp2.h -- it is kept separate because
// it is derived from SWI-Prolog.h

#ifndef _SWI_CPP2_PLX_H
#define _SWI_CPP2_PLX_H

#if PLVERSION >= 90311

/* Wrapper macros - each PL_*() function has a corresponding Plx_*() wrapper:
     PLX_EXCE is for functions whose return code only indicates an error; this error
              is turned into a "throw".
     PLX_WRAP is for functions whose return code could mean either an error or failure
     PLX_ASIS and PLX_VOID are for functions that are used as-is
