PCRE2 - Perl-compatible regular expressions (revised API)
#include <pcre2.h>
pcre2_general_context *pcre2_general_context_copy(
pcre2_general_context *gcontext);
This function makes a new copy of a general context, using the memory allocation
functions in the context, if set, to get the necessary memory. Otherwise
malloc() is used. The result is NULL if the memory cannot 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.
