hdc (HDC) - input

Device context handle.

pptlPosition (PPOINTL) - input

Pointer to new current position.

When COM_TRANSFORM is set, the current position is expressed in world coordinates. Otherwise, this value is passed in device coordinates. The handling routine must transform these values as appropriate. Typically, the presentation driver maintains the current position in both coordinate sets in the DC instance data structure.

pInstance (PVOID) - input

Pointer to instance data.

lFunction (ULONG) - input

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

rc (BOOL) - returns

Return code.

On completion, the handling routine must return a BOOLEAN value to indicate success or an error.

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_BASE_ERROR PMERR_COORDINATE_OVERFLOW
PMERR_DEV_FUNC_NOT_INSTALLED
PMERR_HDC_BUSY
PMERR_INV_COORD_SPACE
PMERR_INV_HDC
PMERR_INV_LENGTH_OR_COUNT
PMERR_PATH_LIMIT_EXCEEDED
