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