 If these routines are used in Pascal programs, then the calling sequence

 The d-option {$d+} allows you to use double precision integers (longs).
 The lseek system call, for instance, needs a long argument and returns a long result.

+All routines put the UNIX error code in the global variable \fIerrno\fP.
 Errno is not cleared by successful system calls, so it always gives
 the error of the last failed call.
 One exception: ptrace clears errno when successful.
