ERRNO - error codes.
Usage:
#include <errno.h>
Description:
This file #defines masks for system error codes and the
"standard" ANSI names for these codes. These include:
- EDOM
- domain error -- a value passed as an argument falls
outside the valid domain for such arguments (e.g. a value
passed to "sqrt" was negative).
- ERANGE
- range error -- the function cannot return a correct
result because the correct result falls outside the range
of values that can be represented by the associated data
type (e.g. if you use the "exp" function on too
large a number).
In addition to these ANSI error values, <errno.h>
defines a few error symbols that match symbols commonly found in
UNIX versions of C. <errno.h> only defines such symbols
when they have close GCOS8 counterparts.

"errno" value.
- expl nsc lib errno
- for information on the format of the NS mode
"errno" value.
