Can I get SSID and MAC address from C code in Linux?

I am writing a C backup program for my Majaro Linux. It must backup files at a certain time in my home local server only if I am connecting to my home network. So I need to get an SSID and a MAC address a current network to decide if it is my network or not.

Is there Linux(Arch) default commands, C library functions or files, contain this information?

I already tried some Linux tools, ifconfig for example, but it is useless for me.

Help!

Done

Thank you all for your help, especially to Iliya Iliev and to this library. It works perfectly.

It exactly what I've been searching for!

I just add it to my main project.

#include "../wifi_scan.h"
#include <stdio.h>  
#include <unistd.h> 

const char *bssid_to_string(const uint8_t bssid[BSSID_LENGTH], char  bssid_string[BSSID_STRING_LENGTH])
    {
        snprintf(bssid_string, BSSID_STRING_LENGTH, "%02x:%02x:%02x:%02x:%02x:%02x",
             bssid[0], bssid[1], bssid[2], bssid[3], bssid[4], bssid[5]);
        printf("%x\n", bssid[5]);
        return bssid_string;
    }

    int main(int argc, char **argv){

        struct wifi_scan *wifi=NULL;
        struct station_info station;
        char mac[BSSID_STRING_LENGTH]; 

        wifi=wifi_scan_init(argv[1]);
        wifi_scan_station(wifi, &station);

        printf("ssid = %s mac = %s \n", station.ssid, bssid_to_string(station.bssid, mac));

        wifi_scan_close(wifi);

    }
