MGL_availablePages

Determine the number of available video pages for a specific graphics mode.

Declaration

int MGLAPI MGL_availablePages(
int mode)

Prototype In

mgraph.h

Parameters

mode | MGL mode number to query

Return Value

Number of available display pages for mode, -1 for invalid mode number.

Description

Returns the number of pages of physical display pages available for a specific MGL graphics mode. You may call this routine before creating a display device context with MGL_createDisplayDC, but you cannot call this function until after you have called MGL_init. This function allows you to ignore display modes that do not have the required number of hardware display pages that your application requires.

Note: If the hardware has not been detected when this call is made, the MGL will automatically detect the installed hardware the first time this function is called.
