Function: read fd buffer

Function: read fd buffer size

Interface to the C function read(), (libc)read. Read bytes from the file descriptor fd and store them in buffer. If successful return a non–negative fixnum representing the number of bytes read, else raise an exception.

buffer and size must represent a generalised C buffer, (vicare-libs)Introduction to generalised C buffers.

Function: pread fd buffer size off
