This function returns the character-set local identifier (lcid), as set by the GpiSetCharSet function.
Syntax
GpiQueryCharSet(hps)
Parameters
- hps (HPS) - input
- Presentation-space handle.
Return Value
- lLcid (LONG) - returns
- Character-set local identifier.
- LCID_DEFAULT - Default
- >0 - Local identifier
- LCID_ERROR - Error.
Remarks
This function is invalid when the drawing mode (see GpiSetDrawingMode) is set to retain.
Errors
Possible returns from WinGetLastError:
- PMERR_INV_HPS (0x207F)
- An invalid presentation-space handle was specified.
- PMERR_PS_BUSY (0x20F4)
- An attempt was made to access the presentation space from more than one thread simultaneously.
- PMERR_INV_IN_RETAIN_MODE (0x208C)
- An attempt was made to issue a function (for example, query) that is invalid when the actual drawing mode is not draw or draw-and-retain.
- PMERR_INV_DC_TYPE (0x2060)
- An invalid type parameter was specified with DevOpenDC, or a function was issued that is invalid for a OD_METAFILE_NOQUERY device context.
Example Code
This example uses GpiQueryCharSet to return the character-set local identifier (lcid), as set by the GpiSetCharSet call.
#define INCL_GPIPRIMITIVES /* Primitive functions */ #include <os2.h> LONG lLcid; /* character set lcid (or error) */ HPS hps; /* Presentation-space handle */ lLcid = GpiQueryCharSet(hps);
