#define Boolean   uchar

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

Referenced by re_cmp(), re_cmp_step(), and re_get_token().

#define False   0

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

Referenced by re_cmp(), re_cmp_step(), re_get_token(), and re_match_token().

#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.

#define SAFE_CHECKS

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

Changing this value will break the code.
