As a special service "Fossies" has tried to format the requested source page into HTML format using (guessed) C and C++ source code syntax highlighting (style: standard) with prefixed line numbers and code folding option. Alternatively you can here view or download the uninterpreted source code file. For more information about "pcre_globals.c" see the Fossies "Dox" file reference documentation.

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

   56 This code used to be here for use when compiling as a C++ library. However,
   57 according to Dair Grant it is not needed: "
   58 
   59  Including 'extern "C"' in the declaration generates an "initialized and
   60  declared `extern'" warning from gcc 4.0.1. Since we include pcre_internal.h,
   61  which includes pcre.h, which declares these prototypes within an extern "C" {}
   62  block, we shouldn't need the prefix here.
   63 
   64 So, from Release 7.0 I have cut this out.
