If there is any nonsense in it,please consult the man page, in case the conversion went wrong.<br><br><b>SYNOPSIS</b><br><P><b>#include <pcre2.h></b></P><P><b>pcre2_jit_stack *pcre2_jit_stack_create(size_t <i>startsize</i>,</b><b> size_t <i>maxsize</i>, pcre2_general_context *<i>gcontext</i>);</b></P><br><b>DESCRIPTION</b><br><P>This function is used to create a stack for use by the code compiled by the JITcompiler. The first two arguments are a starting size for the stack, and amaximum size to which it is allowed to grow. The final argument is a generalcontext, for memory allocation functions, or NULL for standard memoryallocation. 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 anypattern. If the stack couldn't be allocated or the values passed were notreasonable, NULL will be returned.
