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