.SH NAME
kdk_edid_get_interface - 获取显示器的当前接口
.SH SYNOPSIS
.nf
.B #include <libkyedid.h>
.sp
.BI "extern char** kdk_edid_get_interface();"
.sp
Link with \fI\-lkyedid\fP.
.SH "Detailed Description"
The main function of the interface is to obtain the current interface name of the screen.
.SH "RETURN VALUE"
On success, returns a list of current interface name of the screen, ending with a 
.BR NULL
string; Generated by 
.I alloc
and needs to be recycled by 
.BR kdk_edid_freeall
.PP
On error, return
.BR NULL.
