The arguments are a starting size for the stack, and a maximum size to which it is allowed to grow. The result can be passed to the JIT run-time code by <b>pcre[16|32]_assign_jit_stack()</b>, or that function can set up a callback for obtaining a stack. A maximum stack size of 512K to 1M should be more than enough for any pattern. For more details, see the <a href="pcrejit.html"><b>pcrejit</b></a> page. </P> <P> There is a complete description of the PCRE native API in the <a href="pcreapi.html"><b>pcreapi</b></a> page and a description of the POSIX API in the <a href="pcreposix.html"><b>pcreposix</b></a> page. <p> Return to the <a href="index.html">PCRE index page</a>. </p>
