[maemo-developers] Wrting to a text file in N800 /media/mmc1

[From: nisha jain]

Hi Ed,

I just checked too I got this suggestion and tried, it is also not working
:(

I am very amazed why it is not working?  So i am trying following now--

#include<stdio.h>
>>
>> void main()
>> {
>>     FILE *Gfile;
>>     if ((Gfile = fopen("/media/mmc1/test.txt", "w+")) == NULL)
>>     {
>>         printf("Error in file creation");
>>     }
>>
>>     if(Gfile)
>>     fprintf(Gfile,"%02x",0x10);
>>     fclose(Gfile);
>> }

Regards,
Nisha
