ffi_error

NAME

ffi_error() - most recent FFI error message

SYNOPSIS

string ffi_error();

DESCRIPTION

Returns the most recent FFI error message for the current thread —
for example the reason a ffi_load() returned 0 — or the empty string
if there has been no error. Efuns on the FFI surface raise an LPC
error on misuse; ffi_error() reports the failures that are signalled
by a 0 return instead.
