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.
