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
