This function is used to create a stack for use by the code compiled by the JIT |
optimization of \fBpcre_study()\fP. The arguments are a starting size for the | optimization of \fBpcre[16|32]_study()\fP. The arguments are a starting size for |
stack, and a maximum size to which it is allowed to grow. The result can be | the stack, and a maximum size to which it is allowed to grow. The result can be |
passed to the JIT runtime code by \fBpcre_assign_jit_stack()\fP, or that | passed to the JIT run-time code by \fBpcre[16|32]_assign_jit_stack()\fP, or that |
function can set up a callback for obtaining a stack. A maximum stack size of |
function can set up a callback for obtaining a stack. A maximum stack size of |
512K to 1M should be more than enough for any pattern. For more details, see |
