NAME
     xread - read in a fixed sized buffer

SYNOPSIS
     int xread(fd, buf, sz)
     int fd, sz;
     char *buf;

DESCRIPTION
     The xread function reads in at least sz  bytes  from  fd  or
     returns  an  error  code  (-1  for  an error, or 0 for EOF).
     This is done by repeatedly calling read(2) until the  buffer
     has  sz  bytes  in it.  This is useful for reading "packets"
     from a TCP socket because with TCP  message  boundaries  are
     not preserved.

SEE ALSO
     read(2)
