Opens a path bracket in the specified device context
#include <WinAPIGdi.au3>
_WinAPI_BeginPath ( $hDC )
| $hDC | Handle to the device context. |
| Success: | True |
| Failure: | False |
After a path bracket is open, an application can begin calling GDI drawing functions to define the points that lie in the path.
An application can close an open path bracket by calling the _WinAPI_EndPath() function.
When an application calls _WinAPI_BeginPath() for a device context, any previous paths are discarded from that device context.
