Library Functions Manual PCRE2_SET_COMPILE_RECURSION_GUARD(3) NAME PCRE2 - Perl-compatible regular expressions (revised API) SYNOPSIS #include <pcre2.h> int pcre2_set_compile_recursion_guard(pcre2_compile_context *ccontext, int (*guard_function)(uint32_t, void *), void *user_data); DESCRIPTION This function defines, within a compile context, a function that is called whenever pcre2_compile() starts to compile a parenthesized part of a pattern. The first argument to the function gives the current depth of parenthesis nesting, and the second is user data that is sup- plied when the function is set up. The callout function should return zero if all is well, or non-zero to force an error. This feature is provided so that applications can check the available system stack space, in order to avoid running out. The result of pcre2_set_com- pile_recursion_guard() is always zero. There is a complete description of the PCRE2 native API in the pcre2api page and a description of the POSIX API in the pcre2posix page.
