PCRE2 - Perl-compatible regular expressions (revised API)
#include <pcre2.h>
pcre2_general_context *pcre2_general_context_create(
void *(*private_malloc)(PCRE2_SIZE, void *),
void (*private_free)(void *, void *), void *memory_data);
This function creates and initializes a general context. The arguments define
custom memory management functions and a data value that is passed to them
when they are called. The private_malloc() function is used to get
memory for the context. If either of the first two arguments is NULL, the
system memory management function is used. The result is NULL if no memory
could be obtained.
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.
