.SH DESCRIPTION

.rs

|
|
This function is used to create a stack for use by the code compiled by the JIT
|
|
compiler. The first two arguments are a starting size for the stack, and a
|
|
maximum size to which it is allowed to grow. The final argument is a general
|
|
context, for memory allocation functions, or NULL for standard memory
|
|
allocation. The result can be passed to the JIT run-time code by calling
|
|
\fBpcre2_jit_stack_assign()\fP to associate the stack with a compiled pattern,
|
|
which can then be processed by \fBpcre2_match()\fP or \fBpcre2_jit_match()\fP.
|
|
A maximum stack size of 512KiB to 1MiB should be more than enough for any
|
|
pattern. If the stack couldn't be allocated or the values passed were not
|
|
reasonable, NULL will be returned. For more details, see the
