  34. DESCRIPTION
  35. </b><br>
  36. <P>
  37. This function is used to create a stack for use by the code compiled by the JIT
  38. optimization of <b>pcre[16|32]_study()</b>. The arguments are a starting size for
  39. the stack, and a maximum size to which it is allowed to grow. The result can be
  40. passed to the JIT run-time code by <b>pcre[16|32]_assign_jit_stack()</b>, or that
  41. function can set up a callback for obtaining a stack. A maximum stack size of
  42. 512K to 1M should be more than enough for any pattern. For more details, see
  43. the
  44. <a href="pcrejit.html"><b>pcrejit</b></a>
  45. page.
