The very quite good decision. I slightly modified it, so in my opinion
it is more correct.
int fskip(FILE *sf,long num_bytes)
{
char data[1024];
int nskip = 0;
while (num_bytes > 0) {
nskip = (num_bytes>1024) ? 1024 : num_bytes;
num_bytes -= fread(data,(size_t)1,(size_t)nskip,sf);
}
/* return 0 if last read was successful */
return num_bytes;
}
int dummy is not required, as the reading occurs only with current
positions.
My variant with malloc/free was made hastily, only for check of an opportunity
of compilation of the project, and can not apply for the a little correct decision.
As the given function is used very much not frequently, it would be quite possible
to do only fgetc()
PS: sorry my bad english :(
