DESCRIPTION
</b><br>
<P>
This function is used to create a stack for use by the code compiled by the JIT
compiler. The first two arguments are a starting size for the stack, and a
maximum size to which it is allowed to grow. The final argument is a general
context, for memory allocation functions, or NULL for standard memory
allocation. The result can be passed to the JIT run-time code by calling
<b>pcre2_jit_stack_assign()</b> to associate the stack with a compiled pattern,
which can then be processed by <b>pcre2_match()</b>. If the "fast path" JIT
matcher, <b>pcre2_jit_match()</b> is used, the stack can be passed directly as
an argument. A maximum stack size of 512K to 1M should be more than enough for
any pattern. For more details, see the
<a href="pcre2jit.html"><b>pcre2jit</b></a>
page.
