Hi All,
I just checked in N800 the following program for writing into a file which
doesn't work.... Any clues what is going wrong? I neither get any error not
it is
creating a file and writing into it.........
#include<stdio.h>
void main()
{
FILE *Gfile;
if ((Gfile = fopen("/media/mmc1/test.txt", "wt+")) == NULL)
{
printf("Error in file creation");
}
if(Gfile)
fprintf(Gfile,"%02x",0x10);
fclose(Gfile);
}
Regards,
Nisha
