- SYNOPSIS

- <b>#include <pcre2.h></b>

- <P>
- <b>int pcre2_substring_nametable_scan(const pcre2_code *<i>code</i>,</b>
- <b> PCRE2_SPTR <i>name</i>, PCRE2_SPTR *<i>first</i>, PCRE2_SPTR *<i>last</i>);</b>

- DESCRIPTION
- </b><br>
- <P>
- This convenience function finds, for a compiled pattern, the first and last
- entries for a given name in the table that translates capture group names into
- numbers.
- <pre>
- <i>code</i> Compiled regular expression
- <i>name</i> Name whose entries required
- <i>first</i> Where to return a pointer to the first entry
- <i>last</i> Where to return a pointer to the last entry
- </pre>
- When the name is found in the table, if <i>first</i> is NULL, the function
- returns a group number, but if there is more than one matching entry, it is not
- defined which one. Otherwise, when both pointers have been set, the yield of
- the function is the length of each entry in code units. If the name is not
- found, PCRE2_ERROR_NOSUBSTRING is returned.
- </P>
- <P>
- There is a complete description of the PCRE2 native API, including the format of
- the table entries, in the
- <a href="pcre2api.html"><b>pcre2api</b></a>
- page, and a description of the POSIX API in the
- <a href="pcre2posix.html"><b>pcre2posix</b></a>
- page.
