Описание (Description)
This function provides control over the memory used as a stack at
run-time by a call to pcre[16|32]_exec() with a pattern that has
been successfully compiled with JIT optimization. The arguments
are:
extra the data pointer returned by pcre[16|32]_study()
callback a callback function
data a JIT stack or a value to be passed to the callback
function
If callback is NULL and data is NULL, an internal 32K block on
the machine stack is used.
If callback is NULL and data is not NULL, data must be a valid
JIT stack, the result of calling pcre[16|32]_jit_stack_alloc().
If callback not NULL, it is called with data as an argument at
the start of matching, in order to set up a JIT stack. If the
result is NULL, the internal 32K stack is used; otherwise the
return value must be a valid JIT stack, the result of calling
pcre[16|32]_jit_stack_alloc().
You may safely assign the same JIT stack to multiple patterns, as
long as they are all matched in the same thread. In a multithread
application, each thread must use its own JIT stack. 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.
