LONG DTWAIN_GetLibraryPath (

LPTSTR	szBuffer,
LONG	Maxlen );

Parameters

szBuffer

Specifies the address of the character buffer to store the library path name. This parameter can also be NULL.

MaxLen

Specifies the maximum number of characters to copy to szBuffer.

Return Values

If the function succeeds, the number of characters copied to szBuffer is returned. If the function fails, DTWAIN_FAILURE1 is returned.

Character specific version

ANSI version:	DTWAIN_GetLibraryPathA
Unicode version:	DTWAIN_GetLibraryPathW

Comments

The DTWAIN_GetLibraryPath function fills szBuffer with the full path of the DTWAIN DLL that is currently being used.

If szBuffer is NULL, the length of the library path, plus 1 for the trailing NULL, is returned. The MaxLen argument is ignored and no characters are copied to szBuffer. You can use this method to determine the total number of characters needed to store the entire name.

TWAIN State Transitions

None.

Prerequisite Function Call(s)
