This function is used to create a stack for use by the code compiled by the JIT
optimization of pcre[16|32]_study(). 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
pcre[16|32]_assign_jit_stack(), 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 pcrejit page.
There is a complete description of the PCRE native API in the
pcreapi page and a description of the POSIX API in the
pcreposix page.
