Try this.
There are more elegant ways of doing this but I have kept it simple and omitted boundary checks and suchlike so that you should be able to understand the logic.

io_tryread
io_tryread(3) Library Functions Manual io_tryread(3)NAME
io_tryread - read from a descriptor without blocking
SYNTAX
#include <io.h>
int io_tryread(int64 fd,char* buf,int64 len);
DESCRIPTION
io_tryread tries to read len bytes of data from descriptor fd into buf[0], buf[1], ..., buf[len-1]. (The effects are undefined if len is 0
or smaller.) There are several possible results:
o o_tryread returns an integer between 1 and len: This number of bytes was available for immediate reading; the bytes were read into the
beginning of buf. Note that this number can be, and often is, smaller than len; you must not assume that io_tryread always succeeds in
reading exactly len bytes.
o io_tryread returns 0: No bytes were read, because the descriptor is at end of file. For example, this descriptor has reached the end of
a disk file, or is reading an empty pipe that has been closed by all writers.
o io_tryread returns -1, setting errno to EAGAIN: No bytes were read, because the descriptor is not ready. For example, the descriptor is
reading an empty pipe that could still be written to.
o io_tryread returns -3, setting errno to something other than EAGAIN: No bytes were read, because the read attempt encountered a persis-
tent error, such as a serious disk failure (EIO), an unreachable network (ENETUNREACH), or an invalid descriptor number (EBADF).
io_tryread does not pause waiting for a descriptor that is not ready. If you want to pause, use io_waitread or io_wait.
You can make io_tryread faster and more efficient by making the socket non-blocking with io_nonblock().
