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.
