getgraphmode

Returns the current graphics mode.

Defined in header <graphics.h>

Syntax

#include <graphics.h>
int far getgraphmode(void);

Portability

Remarks

Your program must make a successful call to Initgraph before calling getgraphmode.

The enumeration graphicsjnode, defined in graphics.h, gives names for the predefined graphics modes. For a table listing these enumeration values, refer to the description for initgraph.

Return value

getgraphmode returns the graphics mode set by initgraph or setgraphmode.
