! 26: DESCRIPTION
! 27: </b><br>
! 28: <P>
! 29: This function provides control over the memory used as a stack at runtime by a
! 30: call to <b>pcre_exec()</b> with a pattern that has been successfully compiled
! 31: with JIT optimization. The arguments are:
! 32: <pre>
! 33: extra the data pointer returned by <b>pcre_study()</b>
! 34: callback a callback function
! 35: data a JIT stack or a value to be passed to the callback
! 36: function
! 37: </PRE>
! 38: </P>
! 39: <P>
! 40: If <i>callback</i> is NULL and <i>data</i> is NULL, an internal 32K block on
! 41: the machine stack is used.
! 42: </P>
! 43: <P>
! 44: If <i>callback</i> is NULL and <i>data</i> is not NULL, <i>data</i> must
! 45: be a valid JIT stack, the result of calling <b>pcre_jit_stack_alloc()</b>.
! 46: </P>
! 47: <P>
! 48: If <i>callback</i> not NULL, it is called with <i>data</i> as an argument at
! 49: the start of matching, in order to set up a JIT stack. If the result is NULL,
! 50: the internal 32K stack is used; otherwise the return value must be a valid JIT
! 51: stack, the result of calling <b>pcre_jit_stack_alloc()</b>.
! 52: </P>
! 53: <P>
! 54: You may safely assign the same JIT stack to multiple patterns, as long as they
! 55: are all matched in the same thread. In a multithread application, each thread
! 56: must use its own JIT stack. For more details, see the
! 57: <a href="pcrejit.html"><b>pcrejit</b></a>
! 58: page.
