int LSL_loadHSL	(	const char *	libname,
		char *	msgbuf,
		int	msglen
	)

Tries to load a dynamically linked library with HSL routines.

Also tries to load symbols for those HSL routines that are not linked into Ipopt, i.e., HAVE_... is not defined. Return a failure if the library cannot be loaded, but not if a symbol is not found.

LSL_isMA27available

LSL_isMA28available

LSL_isMA57available

LSL_isMC19available

Parameters:

	libname	The name under which the HSL lib can be found, or NULL to use a default name (libhsl.<SHAREDLIBEXT>).
	msgbuf	A buffer where we can store a failure message. Assumed to be NOT NULL!
	msglen	Length of the message buffer.

Returns:

Zero on success, nonzero on failure.

int LSL_unloadHSL

(

)

Unloads a loaded HSL library.

Returns:

Zero on success, nonzero on failure.

int LSL_isHSLLoaded

(

)

Indicates whether a HSL library has been loaded.

Returns:

Zero if not loaded, nonzero if handle is loaded

int LSL_isMA27available

(

)

Indicates whether a HSL library is loaded and all symbols necessary to use MA27 have been found.

Returns:

Zero if not available, nonzero if MA27 is available in the loaded library.

int LSL_isMA28available

(

)

Indicates whether a HSL library is loaded and all symbols necessary to use MA28 have been found.

Returns:

Zero if not available, nonzero if MA28 is available in the loaded library.

int LSL_isMA57available

(

)

Indicates whether a HSL library is loaded and all symbols necessary to use MA57 have been found.

Returns:

Zero if not available, nonzero if MA57 is available in the loaded library.

int LSL_isMC19available

(

)

Indicates whether a HSL library is loaded and all symbols necessary to use MA57 have been found.

Returns:

Zero if not available, nonzero if MA57 is available in the loaded library.

char* LSL_HSLLibraryName

(

)

Returns name of the shared library that should contain HSL.
