how to use the fread() function???

[system55]

Pls help me..... I need to read 131067 items with a size of 1 byte each item...
if(fread((void *) pBuffer,1,512*256,pGList)==0)
{
cout<<"Cannot read file";
return -1;
}
is this code correct?????

Well 512 * 256 = 131072 not 131067 so the size is wrong

and since you have not told us how pBuffer and pGList are declared it is impossible to tell.

sorry if i lack the declaration of the pBuffer and pGList...
by d way this is hw i declare it....

unsigned char huge *pBuffer;
file *pGLIst;
if((pGList= fopen("glist.bin", "rb"))==NULL)
cout<<"Error opening file";
pBuffer=(unsigned char huge *) farcalloc(0x20000,1);
if(pBuffer==NULL)
cout<<"Insuficient Memory";
if(fread((void *) pBuffer,1,512*256,pGList)==0)
cout<<"Cannot read file";
return -1;
}

looks more or less right, if pBuffer is NULL then you still try to use it which will fail nastily
