SCIPincludeReader()

SCIP_RETCODE SCIPincludeReader	(	SCIP *	scip,
		const char *	name,
		const char *	desc,
		const char *	extension,
		SCIP_DECL_READERCOPY((*readercopy))	,
		SCIP_DECL_READERFREE((*readerfree))	,
		SCIP_DECL_READERREAD((*readerread))	,
		SCIP_DECL_READERWRITE((*readerwrite))	,
		SCIP_READERDATA *	readerdata
	)

creates a reader and includes it in SCIP

Returns

SCIP_OKAY is returned if everything worked. Otherwise a suitable error code is passed. See SCIP_RETCODE for a complete list of error codes.

Precondition

This method can be called if SCIP is in one of the following stages:

• SCIP_STAGE_INIT
• SCIP_STAGE_PROBLEM

Note

method has all reader callbacks as arguments and is thus changed every time a new callback is added in future releases; consider using SCIPincludeReaderBasic() and setter functions if you seek for a method which is less likely to change in future releases

Parameters

scip	SCIP data structure
name	name of reader
desc	description of reader
extension	file extension that reader processes
readerdata	reader data

Definition at line 5159 of file scip.c.

References checkStage(), FALSE, NULL, SCIP_CALL, SCIP_INVALIDDATA, SCIP_OKAY, SCIPerrorMessage, SCIPfindReader(), SCIPreaderCreate(), SCIPsetIncludeReader(), Scip::set, and TRUE.

SCIPincludeReaderBasic()

SCIP_RETCODE SCIPincludeReaderBasic	(	SCIP *	scip,
		SCIP_READER **	readerptr,
		const char *	name,
		const char *	desc,
		const char *	extension,
		SCIP_READERDATA *	readerdata
	)

creates a reader and includes it in SCIP. All non-fundamental (or optional) callbacks will be set to NULL. Optional callbacks can be set via specific setter functions, see SCIPsetReaderCopy(), SCIPsetReaderFree(), SCIPsetReaderRead(), SCIPsetReaderWrite().

Returns

SCIP_OKAY is returned if everything worked. Otherwise a suitable error code is passed. See SCIP_RETCODE for a complete list of error codes.

Precondition

This method can be called if SCIP is in one of the following stages:

• SCIP_STAGE_INIT
• SCIP_STAGE_PROBLEM

Note

if you want to set all callbacks with a single method call, consider using SCIPincludeReader() instead

Parameters

scip	SCIP data structure
readerptr	reference to reader pointer, or NULL
name	name of reader
desc	description of reader
extension	file extension that reader processes
readerdata	reader data

Definition at line 5201 of file scip.c.
