19 This function sets the match context fields for custom memory manage‐
20 ment when PCRE2 is compiled to use the heap instead of the system stack
21 for recursive function calls while matching. When PCRE2 is compiled to
22 use the stack (the default) this function does nothing. The first argu‐
23 ment is a match context, the second and third specify the memory allo‐
24 cation and freeing functions, and the final argument is an opaque value
25 that is passed to them whenever they are called. The result of this
26 function is always zero.

29 page and a description of the POSIX API in the pcre2posix page.
