/* This is the original "info" function. It picks potentially useful data out
|
|
of the private structure, but its interface was too rigid. It remains for
|
|
backwards compatibility. The public options are passed back in an int - though
|
|
the re->options field has been expanded to a long int, all the public options
|
|
at the low end of it, and so even on 16-bit systems this will still be OK.
|
|
Therefore, I haven't changed the API for pcre_info().
|
|
|
|
Arguments:
|
|
argument_re points to compiled code
|
|
optptr where to pass back the options
|
|
first_byte where to pass back the first character,
|
|
or -1 if multiline and all branches start ^,
|
|
or -2 otherwise
|
|
|
|
Returns: number of capturing subpatterns
|
|
or negative values on error
