NAME ^

src/extend.c - Parrot extension interface

DESCRIPTION ^

These are the functions that parrot extensions (i.e. parrot subroutines written in C, or some other compiled language, rather than in parrot bytecode) may access.

There is a deliberate distancing from the internals here. Don't go peeking inside -- you've as much access as bytecode does, but no more, so we can provide backwards compatibility for as long as we possibly can.

Functions ^

*/

/* Some internal notes. Parrot will die a horrible and bizarre death if the stack start pointer's not set and a DOD run is triggered. The pointer *will* be set by the interpreter if the interpreter calls code which calls these functions, so most extension code is safe, no problem.

   The problem comes in if these routines are called from *outside*
   an interpreter. This happens when an embedding application calls
   them to do stuff with PMCs, STRINGS, interpreter contents, and
   suchlike things. This is perfectly legal -- in fact it's what
   we've documented should be done -- but the problem is that the
   stack base pointer will be NULL. This is Very Bad.

   To deal with this there are two macros that are defined to handle
   the problem.

   PARROT_CALLIN_START(interp) will figure out if the stack
   anchor needs setting and, if so, will set it. It must *always*
   come immediately after the last variable declared in the block
   making the calls into the interpreter, as it declares a variable
   and has some code.

   PARROT_CALLIN_END(interp) will put the stack anchor back to
   the way it was, and should always be the last statement before a
   return. (If you have multiple returns have it in multiple times)

   Not doing this is a good way to introduce bizarre heisenbugs, so
   just do it. This is the only place they ought to have to be put
   in, and most of the functions are already written, so it's not
   like it's an onerous requirement.
