.SH NAME
kdk_system_get_kernelVersion - 获取内核版本号
.SH SYNOPSIS
.nf
.B #include <libkysysinfo.h>
.sp
.BI "extern char* kdk_system_get_kernelVersion();" 
.sp
Link with \fI\-lkysysinfo\fP.
.SH "Detailed Description"
The main function of the interface is to obtain kernel version number.
.SH "RETURN VALUE"
On success, returns kernel version number of type char*; The returned string needs to be released by
.I free
.
.PP
On error, return
.BR NULL.
