SYS-WERRSTR(2)SYS-WERRSTR(2)NAME
werrstr - set the system error string
SYNOPSIS
include "sys.m";
sys := load Sys Sys->PATH;
werrstr(s: string): int;
DESCRIPTION
When a system call fails, it returns an error value (often -1) and
records a string describing the error in a per-process location. The
verb r in sys-print(2) outputs the error string. Werrstr sets the
process's error string to s, to allow a function in a module to mimic
the error reporting interface of a system call.
