PCRE2_SET...E_CALLOUT(3) Library Functions ManualPCRE2_SET...E_CALLOUT(3)
       PCRE2 - Perl-compatible regular expressions (revised API)
       #include <pcre2.h>
       int pcre2_set_substitute_callout(pcre2_match_context *mcontext,
         int (*callout_function)(pcre2_substitute_callout_block *, void *),
         void *callout_data);
       This function sets the substitute 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.
