NAME
error - generate a value of specified error type
SYNOPSIS
error([n])
TYPES
n integer, 0 <= n <= 32767; defaults to errno()
return null value or error value
DESCRIPTION
If n is zero, error(n) returns the null value.
For positive n, error(n) returns a value of error type n.
error(n) sets calc_errno to n so that until another error-value
is returned by some function, errno() will return the value n.
EXAMPLE
Note that by default, errmax() is 0 so unless errmax() is
increased you will get:
; ba = error(10009)
Error 10009 caused errcount to exceed errmax
; errmax(errcount()+1)
0
; a = error(10009)
; a
Error 10009
LIMITS
none
LINK LIBRARY
