EXAMPLE

#include <libconfig.h>
#include <stdlib.h>
#include <stdio.h>

int main(int argc, char **argv) {
        int lc_p_ret, lc_rv_ret;
        char *filename = NULL;

        lc_rv_ret = lc_register_var("File", LC_VAR_STRING,
                                    &filename, 'f');
        if (lc_rv_ret != 0) {
                fprintf(stderr, "Error registering variable: %i.\n",
                        lc_geterrno());
                return(EXIT_FAILURE);
        }

        lc_p_ret = lc_process_file("example", "/data/extra.conf",
                                   LC_CONF_APACHE);

        lc_cleanup();

        if (lc_p_ret != 0) {
                fprintf(stderr, "Error processing configuration file: \
                        %s\n", lc_geterrstr());
                return(EXIT_FAILURE);
        }

        if (filename != NULL) {
                printf("File specified was: %s\n", filename);
        } else {
                printf("No filename specified.\n");
        }

        return(EXIT_SUCCESS);
}
