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
