pmrg (PMARGSTRUCT)

Margin structure.

param2 contains pmrg for a usnotifycode of MLN_MARGIN.

The left and right margins are defined as going all the way to the top and bottom such that the top and bottom margins are contained between them. Therefore, the corners are included in the sides.

usMouMsg contains the mouse message that signals the event.

iptNear contains the insertion point of the nearest point in the text. For situations where the nearest location is beyond the end of a line, the insertion point for the end of the line is returned. (The EOL character is considered to be beyond the end of the line.)
