.SH DESCRIPTION
|

|
|
.rs
|
||
|
|
.sp
|
||
|
|
This function sets the match context fields for custom memory management when
|
||
|
|
PCRE2 is compiled to use the heap instead of the system stack for recursive
|
||
|
|
function calls while matching. When PCRE2 is compiled to use the stack (the
|
||
|
|
default) this function does nothing. The first argument is a match context, the
|
||
|
|
second and third specify the memory allocation and freeing functions, and the
|
||
|
|
final argument is an opaque value that is passed to them whenever they are
|
||
|
|
called. The result of this function is always zero.
