Detailed Description
接口的主要功能是获取指定配置项的值
Examples
#include <libkyconf.h>
#include <stdio.h>
#include <string.h>
int main()
{
char **keylist = NULL;
int id = kdk_conf_init("struct.conf");
ASSERT_NOT_NULL(id, -1);
char **grouplist = kdk_conf_list_group(id);
ASSERT_NOT_NULL(grouplist, -1);
char *tmpgroup;
int index = 0;
while ((tmpgroup = grouplist[index]))
{
printf("Group: %s0, tmpgroup);
keylist = kdk_conf_list_key(id, tmpgroup);
ASSERT_NOT_NULL(keylist, -1);
char *tmpkey;
int k_index = 0;
while ((tmpkey = keylist[k_index]))
{
const char *tmpval = kdk_conf_get_value(id, tmpgroup, tmpkey);
printf("%s = %s0, tmpkey , tmpval);
k_index ++;
}
kdk_config_freeall(keylist);
index ++;
}
kdk_conf_destroy(id);
kdk_config_freeall(grouplist);
return 0;
