.SH NAME
kdk_net_get_hosts - 获取hosts配置
.SH SYNOPSIS
.nf
.B #include <libkynetinfo.h>
.sp
.BI "extern char* kdk_net_get_hosts();" 
.sp
Link with \fI\-lkynetinfo\fP.
.SH "Detailed Description"
The main function of the interface is to obtain the hosts configuration.
.SH "RETURN VALUE"
On success, returns the hosts configuration of type char *; The returned string needs to be released by
.I free
.PP
On error, return
.BR NULL.
