| .SH DESCRIPTION |
| .rs |
| .sp |
| This function is used to create a stack for use by the code compiled by the JIT |
| optimization of \fBpcre[16|32]_study()\fP. The arguments are a starting size for |
| the stack, and a maximum size to which it is allowed to grow. The result can be |
| 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 |
| 512K to 1M should be more than enough for any pattern. For more details, see |
| the |
