NAME

lc_process_file - Process a specific file

 

SYNOPSIS

#include <libconfig.h>

int lc_process_file(const char *appname, const char *pathname, lc_conf_type_t type);

 

DESCRIPTION

The lc_process_file(3) function processes exactly one configuration file. The file is specified by the pathname argument and should be in the format specified by the type argument. The appname argument should be a reasonable form of the name of the application.

 

RETURN VALUE

On success 0 is returned, otherwise -1 is returned.

 

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);
}
