GRX_TEST module routines

GRX_TEST module routines - WIN32

grx_test.c -

This is a simple testbed that I used to first develop the graphic window routines. I have included it as a sample program since it shows examples of a number of low level calls into the G_WIN subsystem and direct window handling. High level examples can be found in SNAPSHOT.C. This is NOT a finished or polished app (but just a QND hack :-)

Function	pack
Include file	GRX_TEST.H
Prototype	#pragma pack( 4 )
Remarks

Function	WinMain
Include file	GRX_TEST.H
Prototype	int PASCAL WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpszCmdLine, int nCmdShow )
Remarks	Main entry.

Function	process_cmd_line_4_arguments
Include file	GRX_TEST.H
Prototype	void process_cmd_line_4_arguments( LPSTR lpCmdLine )
Remarks	Process the user's command line arguments into a argv array which then is processed by the normal getargs() procedure to store the data into the programs switch flags.

Function	localGWndProc
Include file	GRX_TEST.H
Prototype	LONG WINAPI localGWndProc( HWND hWnd , UINT messg , UINT wParam , LONG lParam )
Remarks	This is the local G_WIN WinProc. It just handles keyboard input to honor exit requests.

Function	test_routine1
Include file	GRX_TEST.H
Prototype	void test_routine1( G_WIN *w_ptr )
Remarks

Function	control_c_handler
Include file	GRX_TEST.H
Prototype	BOOL WINAPI control_c_handler( DWORD dwCtrlType )
Remarks	A simple windows control-c catcher. It currently doesn't do much - just signal the event out the DB msg port.

Function	calc_cycle_position
Include file	GRX_TEST.H
Prototype	float calc_cycle_position( int cycle_length , int cur_offset )
Remarks	Calculate the current position in a cycle, return x where 1 >= x >= -1 with 1 = top of the cycle & -1 = bottom of the cycle.
