.SH NAME
kdk_edid_get_resolution - 获取分辨率
.SH SYNOPSIS
.nf
.B #include <libkyedid.h>
.sp
.BI "extern char* kdk_edid_get_resolution(char *"name ");"
.sp
Link with \fI\-lkyedid\fP.
.SH "Detailed Description"
The main function of the interface is to obtain the resolution of the screen.
.PP
The argument
.I name
is the current interface of the screen.
.SH "RETURN VALUE"
On success, returns the resolution of type char*; The returned string needs to be released by
.I free
.PP
On error, return
.BR NULL.
