GetKerningPairs info Overview Group

The GetKerningPairs function retrieves the character-kerning pairs for the currently selected font for the specified device context.

DWORD GetKerningPairs(

HDC hdc,	// handle of device context
DWORD nNumPairs,	// number of kerning-pairs to be retrieved
LPKERNINGPAIR lpkrnpair	// address of kerning-pair array
);

Parameters

hdc: Identifies the device context.
nNumPairs: Specifies the number of pairs that fit in the lpkrnpair array. If the font has more than nNumPairs kerning pairs, an error is returned.
lpkrnpair: Points to an array of KERNINGPAIR structures to receive the kerning pairs. The array must contain at least as many structures as specified by the nNumPairs parameter. If this parameter is NULL, the function returns the total number of kerning pairs for the font.

If the function succeeds, the return value is the number of kerning pairs returned.

If the function fails, the return value is zero. To get extended error information, call GetLastError.
