<H2>DESCRIPTION</H2>
<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> or <B>pcre2_jit_match()</B>.
A maximum stack size of 512KiB to 1MiB should be more than enough for any
pattern. For more details, see the
<B>pcre2jit</B>
page.
<P>
There is a complete description of the PCRE2 native API in the
<B>pcre2api</B>
page and a description of the POSIX API in the
<B>pcre2posix</B>
page.
