Device context handle.

lSrc (LONG) - input

Source-coordinate space.

CVTC_WORLD

World-coordinate space
CVTC_MODEL
Model space
CVTC_DEFAULTPAGE
Default page-coordinate space
CVTC_PAGE
Page-coordinate space
CVTC_DEVICE
Device-coordinate space. Screen coordinates are 32-bit signed integers and are used by the presentation driver as screen pel addresses.

lDst (LONG) - input

Target-coordinate space. Defined by the same values as lSrc.

paptlPoint (PPOINTL) - input

Pointer to array of (x, y) coordinates to transform. The result is also returned to this parameter.

cPoints (LONG) - input

Count of coordinate pairs in the array.

pInstance (PVOID) - input

Pointer to instance data.

lFunction (ULONG) - input

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

fSuccess (BOOL) - returns

This function returns BOOLEAN (fSuccess).

TRUE

Successful
FALSE
Error

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