pcre2_get_ovector_count returns a uint32_t and callout_number is
uint32_t, but the number parameter for the following functions is
unsigned int:
pcre2_substring_copy_bynumber
pcre2_substring_get_bynumber
pcre2_substring_length_bynumber
Shouldn't that be the same types?

int pcre2_dfa_match(const pcre2_code *code, PCRE2_SPTR subject,
PCRE2_SIZE length, PCRE2_SIZE startoffset, uint32_t options,
pcre2_match_data *match_data, pcre2_match_context *mcontext, int
*workspace, PCRE2_SIZE wscount);
workspace Points to a vector of ints used as working space
wscount Number of elements in the vector
Are ints always enough? I am not familiar enough with the code to know
what constraints there might be that are related to match
positions/ovectors etc.

I would reorder the information a little, I got confused reading it the
first time.

DESCRIPTION
This function returns information about a compiled pattern. Its
arguments are:
code Compiled regular expression
what What information is required
where Where to put the information
<<<<Unchanged
The possible what constants and the information they request is:
/what/ requested information
<entry1 what value> <entry1 info>
<entry2 what value> <entry2 info>
<entry3 what value> <entry3 info>
.
.
.
<=unchanged what/information table>
If where is NULL, the function returns the amount of memory needed for
the requested information, in bytes. The where argument must point to an
unsigned 32-bit integer (uint32_t variable), except for the following
what values:
PCRE2_INFO_FIRSTBITMAP const uint8_t *
PCRE2_INFO_JITSIZE size_t
PCRE2_INFO_NAMETABLE PCRE2_SPTR
PCRE2_INFO_SIZE size_t
