Trying to make changes in wireless configuration using UCI library function calls

For Developers

Hi,

I am trying to wrote a wrapper for UCI library calls for changing wireless configuration.

This is my wrapper .c file

#include <stdio.h>
#include <string.h>


#ifdef __cplusplus
extern "C" {
#endif

#include <uci.h>

void main ()
{
	printf ("You are in UCI API APPLICATION FILE\n");
	char path[]="wireless.@wifi-iface[0].mode";
   char buffer[80];
   struct  uci_ptr ptr;
   struct  uci_context *c = uci_alloc_context();

   if(!c) return;

   if ((uci_lookup_ptr(c, &ptr, path, true) != UCI_OK) ||
         (ptr.o==NULL || ptr.o->v.string==NULL))
   {
     uci_free_context(c);
     return;
   }

   if(ptr.flags & UCI_LOOKUP_COMPLETE)
      strcpy(buffer, ptr.o->v.string);

   printf("%s\n", buffer);

   // setting UCI values
   // -----------------------------------------------------------
   // this will set the value to 1234
   ptr.value = "1234";

if ((uci_set(c, &ptr) != UCI_OK) ||
        (ptr.o == NULL || ptr.o->v.string == NULL ))
    {
        uci_free_context(c);
        return;
    }

   // commit your changes to make sure that UCI values are saved
   if (uci_commit(c, &ptr.p, false) != UCI_OK)
   {
      uci_free_context(c);
      uci_perror(c,"UCI Error");
      return;
   }

   uci_free_context(c);

	return;
}

#ifdef __cplusplus
}
#endif

My changes are getting reflected in file but how to apply those changes.
Please can anyone help me in this.
Thanks in advance.

AFAIK you need to restart the radio by calling /sbin/wifi, optionally with the specific radio, like /sbin/wifi radio0.
