GpiQueryNumberSetIds

This function returns the number of local identifiers (lcids) currently in use, referring to fonts or bit maps.

Syntax

GpiQueryNumberSetIds(hps)

Parameters

hps (HPS) - input

Presentation-space handle.

Return Value

lCount (LONG) - returns

Number of lcids.

>=0

Number of lcids in use

GPI_ALTERROR

Error.

Remarks

LCID_DEFAULT is included if the default font has been changed (see GpiCreateLogFont). The information returned by this call can be used to perform a subsequent GpiQuerySetIds request.

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.

Example Code

#define INCL_GPILCIDS /* Or use INCL_GPI, INCL_PM, */
#include <os2.h>

HPS     hps;    /* Presentation-space handle. */
LONG    lCount; /* Number of lcids. */

lCount = GpiQueryNumberSetIds(hps);

This example uses GpiQueryNumberSetIds to return the number of local identifiers in use (font and bit map).

#define INCL_GPILCIDS /* Font functions */
#include <os2.h>

LONG lCount; /* number of lcid's */
HPS hps; /* Presentation-space handle */

lCount = GpiQueryNumberSetIds(hps);
