When PCRE2 is compiled to use the stack (the 34default) this function does nothing. The first argument is a match context, the 35second and third specify the memory allocation and freeing functions, and the 36final argument is an opaque value that is passed to them whenever they are 37called. The result of this function is always zero. 38</P> 39<P> 40There is a complete description of the PCRE2 native API in the 41<a href="pcre2api.html"><b>pcre2api</b></a> 42page and a description of the POSIX API in the 43<a href="pcre2posix.html"><b>pcre2posix</b></a> 44page. 45<p> 46Return to the <a href="index.html">PCRE2 index page</a>. 47</p> 48
