int GXComputeLineBreaks(CDC* pDC, LPCTSTR sz, int nCount, LPRECT rc, UINT nFormat, int* LineBreaks, int* LineLengths, int nMaxBreaks);

pDC

Points to the device context.

Points to the text to be drawn.

nCount

Specifies the size of the text in bytes. You should pass -1 for a zero-terminated string.

Drawing rectangle.

nFormat

Format:

DT_CENTERcentered
DT_RIGHTright aligned
DT_TOPtop aligned
DT_VCENTERvertically centered
DT_BOTTOMbottom aligned

LineBreaks

Pointer to an integer where the number of necessary line breaks will be returned. Must not be NULL.

LineLengths

Pointer to an array of integers where the line break positions will be returned.

nMaxBreaks

The size of the integer array.

Return Value

The number of line breaks.
