fSuccess (BOOL) - returns

Return codes.

This function returns BOOLEAN (fSuccess).

TRUE

Successful
FALSE
Error

PMERR_HDC_BUSY
PMERR_INSUFFICIENT_MEMORY
PMERR_INV_COORD_SPACE
PMERR_INV_COORDINATE
PMERR_INV_HDC
PMERR_INV_HRGN
PMERR_INV_IN_AREA
PMERR_INV_IN_PATH
PMERR_INV_LENGTH_OR_COUNT
PMERR_INV_MATRIX_ELEMENT
PMERR_INV_PATTERN_REF_PT_ATTR
PMERR_INV_PICK_APERTURE_POSN
PMERR_INV_RECT
