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_ALREADY_IN_AREA
PMERR_BASE_ERROR
PMERR_COORDINATE_OVERFLOW
PMERR_DEV_FUNC_NOT_INSTALLED
PMERR_HDC_BUSY
PMERR_INV_AREA_CONTROL
PMERR_INV_COORD_SPACE
PMERR_INV_HDC
PMERR_INV_IN_PATH
PMERR_INV_LENGTH_OR_COUNT
PMERR_PATH_LIMIT_EXCEEDED
