KDK_EDID_GET_PRIMARY(3)    Library Functions Manual    KDK_EDID_GET_PRIMARY(3)

NAME
       kdk_edid_get_primary - <?><?><?><?><?><?><?><?><?><?><?>/<?><?>

SYNOPSIS
       #include <libkyedid.h>

       extern int kdk_edid_get_primary(char *name);

       Link with -lkyedid.

Detailed Description
       The main function of the interface is to determine whether it is the
       main screen.

       The argument name is the current interface of the screen.

RETURN VALUE
       On success, returns 1, which is the primary screen; Returns 0, not the
       primary screen.  On error, return -1.
