i am getting junk value in file,if i write a integers to file.can body tell me what's the prob.

int main ()
{
    FILE*          fp = NULL; 
    UINT32         data[4];
 
    UINT32         i = 0;
    UINT32         res[MAX_SIZE];
    UZN_STATUS       status = UZN_SUCCESS;
    UINT32         count = 0;
    /*Creating file called x*/
 
    memset (data, 0, sizeof(data));
    fp = fopen ("x.bin", "wb");
    data[0]=1;
    data[1]=2;
    data[2]=3;
    data[3]=4;
    if (fp == NULL)
    {
        printf("File open failed\n");
        return -1
    }
 
 
 
         count=fwrite (data, sizeof(UINT32), 1,fp);
        printf("%d", count);
    /*Reading from that same file*/ 
    fread(res,sizeof(UINT32),4,fp)
   for(i=0; i<4; i++)
    {
 
       printf("%8.8x\t",res[i]);
    }
    fclose (fp);
}

a12b12,

Looks like you forgot to seek to the start of the file before you started reading.

Try looking at this reference on fseek().

Cheers!

On line 26 you write one UINT32; but on line 29 you read four UNIT32's.

This is not causing your problem, but it is a good idea for newline ('\n') to be the last character you write to stdout (lines 27 and 33). In some implementations, nothing is visible on stdout until a newline is written.
