KDK_EDID_GET_GAMMA(3)      Library Functions Manual      KDK_EDID_GET_GAMMA(3)

NAME
       kdk_edid_get_gamma - <?><?><?><?><?><?><?><?><?>

SYNOPSIS
       #include <libkyedid.h>

       extern float kdk_edid_get_gamma(char *name);

       Link with -lkyedid.

Detailed Description
       The main function of the interface is to obtain the gamma value of the
       screen.

       The argument name is the current interface of the screen.

RETURN VALUE
       On success, returns the screen gamma value of type float.

       On error, return 0.00.
