errcount - return or set the internal error count
SYNOPSIS
errcount([num])
TYPES
num integer
return integer
DESCRIPTION
An internal variable keeps count of the number of functions
evaluating to an error value either internally or by a call to
error() or newerror().
The errcount() with no args returns the current error count. Calling
errcount(num) returns the current error count and resets it to num.
If the count exceeds the current value of errmax, execution is aborted
with a message displaying the errno for the error.
If an error value is assigned to a variable as in:
infty = 1/0;
then a function returning that variable does not contribute to
errcount.
EXAMPLE
; errmax(10)
0
; errcount()
0
; a = 1/0; b = 2 + ""; c = error(27); d = newerror("a");
; print errcount(), a, errcount(), errmax();
4 Error 10001 4 10
LIMITS
0 <= num < 2^32
LINK LIBRARY
none
