Macro Definition Documentation

Boolean

#define Boolean   uchar

Definition at line 43 of file re-cmp.h.

False

#define False   0

Definition at line 45 of file re-cmp.h.

RE_TOKEN_MAX

#define RE_TOKEN_MAX   64

Max amount of tokens in a regexp. Each token uses ~264 bytes. They are allocated as needed, but never de-allocated. E.g. [A-Za-z0-9_] counts as one token, so 64 should be plenty for most purposes.

Definition at line 19 of file re-cmp.h.

SAFE_CHECKS

#define SAFE_CHECKS

Regexp's with syntax errors will core dump if this is undefined.

Definition at line 15 of file re-cmp.h.

True

#define True   1

Changing this value will break the code

Definition at line 44 of file re-cmp.h.

uchar

#define uchar   unsigned char
