When PCRE2 is compiled to use the stack (the default) this function does nothing. The first argument is a match context, the second and third specify the memory allocation and freeing functions, and the final argument is an opaque value that is passed to them whenever they are called. The result of this function is always zero. </P> <P> There is a complete description of the PCRE2 native API 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. <p> Return to the <a href="index.html">PCRE2 index page</a>. </p>
