hdc (HDC) - input

Device context handle.

cKernPairs (LONG) - input

Number of kerning pairs requested by the application.

pKernPairs (PKERNPAIRS) - input

Pointer to kerning pair records.

KERNINGPAIRS data structure:

sFirstChar

Code point for the first character
sSecondChar
Code point for the second character
sKerningAmount
Two-byte signed integer indicating the amount of kerning. Positive numbers specify increased inter-character spacing.

pInstance (PVOID) - input

Pointer to instance data.

lFunction (ULONG) - input

High-order WORD=flags;. low-order WORD=NGreGetPairKerningTable.

rc (LONG) - returns

Return Code.

On completion, the handling routine must return the number of kerning pairs returned in pKernPairs (cPairs), or GPI_ALTERROR if an error occurs.

Possible Errors Detected: When an error is detected, the handling routine must call WinSetErrorInfo to post the condition. Error codes for conditions that the handling routine is expected to check include:

PMERR_COORDINATE_OVERFLOW PMERR_DEV_FUNC_NOT_INSTALLED
PMERR_EXCEEDS_MAX_SEG_LENGTH
PMERR_HDC_BUSY
PMERR_INSUFFICIENT_MEMORY
PMERR_INV_CODEPAGE
PMERR_INV_COORD_SPACE
PMERR_INV_HDC
PMERR_INV_LENGTH_OR_COUNT
PMERR_INV_SETID

Refer to the "Error Explanations" section in the Presentation Manager Programming Reference for further explanation.
