Simulation support:

This function is simulated by a handling routine in the graphics engine.

Description

GreBeginPath identifies the start of a sequence of figures that define a path. Note that functions that set character attributes are not allowed within a path definition. When GreBoxxxx or GreFullArcxxx functions are used within a path definition, they generate closed figures and must not be used within another figure definition. Refer to function "GpiBeginPath" in the Presentation Manager Programming Reference for further information.

This function can be hooked by the presentation driver.
