PCRE2_SET_CALLOUT(3)       Library Functions Manual       PCRE2_SET_CALLOUT(3)

       PCRE2 - Perl-compatible regular expressions (revised API)


       #include <pcre2.h>

       int pcre2_set_callout(pcre2_match_context *mcontext,
         int (*callout_function)(pcre2_callout_block *),
         void *callout_data);


       This  function  sets  the  callout fields in a match context (the first
       argument).  The second argument specifies a callout function,  and  the
       third  argument is an opaque data item that is passed to it. The result
       of this function is always zero.

       There is a complete description of the PCRE2 native API in the pcre2api
       page and a description of the POSIX API in the pcre2posix page.
