43 /* This module contains global variables that are exported by the PCRE library.
44 PCRE is thread-clean and doesn't use any global variables in the normal sense.
45 However, it calls memory allocation and freeing functions via the four
46 indirections below, and it can optionally do callouts, using the fifth
47 indirection. These values can be changed by the caller, but are shared between
48 all threads. However, when compiling for Virtual Pascal, things are done
49 differently, and global variables are not used (see pcre.in). */
