 Question about sbrk()
I can't compile the malloc program given in Section 8.7 of K&R. I have
included header file unistd.h but gcc told me that sbrk() is not
defined.

if ch 8 is the one I think it is, then this is offtopic in CLC since
it relates to Unix specific stuff. However I suspect that the answer
to your question is that K&R wrote for one flavour of Unix, and you're
using a different one, linux at a guess. Unices are not all the same
and nor are their compiler environments.

Perhaps you intended to use strpbrk() (defined in string.h) ? Otherwise,
neither the function nor the header (unistd.h) are standard C.
Cheers,

Question about sbrk()
doesn't sound like I. Must be a human:

find /usr/include -name '*.h' | xargs grep sbrk

declared in unistd.h AFAICT. So it may or may not be Linux or
else, it may also be a Winloose gcc that complaines, but than it
would probably have had problems with the header-include prior
to the functions use.
