view release on metacpan or search on metacpan
(1) The plugin must not use malloc(), free() or other heap memory
management within its run() or run_adding() functions. All new
memory used in run() must be managed via the stack. These
restrictions only apply to the run() function.
(2) The plugin will not attempt to make use of any library
functions with the exceptions of functions in the ANSI standard C
and C maths libraries, which the host is expected to provide.
(3) The plugin will not access files, devices, pipes, sockets, IPC
or any other mechanism that might result in process or thread
blocking.
(4) The plugin will take an amount of time to execute a run() or
run_adding() call approximately of form (A+B*SampleCount) where A
and B depend on the machine and host in use. This amount of time
may not depend on input signals or plugin state. The host is left
the responsibility to perform timings to estimate upper bounds for
A and B. */

/*
* Boilerplate macros for initializing and accessing interpreter-local
* data from C. All statics in extensions should be reworked to use
* this, if you want to make the extension thread-safe. See ext/re/re.xs
* for an example of the use of these macros.
*
* Code that uses these macros is responsible for the following:
* 1. #define MY_CXT_KEY to a unique string, e.g. "DynaLoader_guts"
* 2. Declare a typedef named my_cxt_t that is a structure that contains
* all the data that needs to be interpreter-local.
* 3. Use the START_MY_CXT macro after the declaration of my_cxt_t.
* 4. Use the MY_CXT_INIT macro such that it is called exactly once
* (typically put in the BOOT: section).
* 5. Use the members of the my_cxt_t structure everywhere as
* 6. Use the dMY_CXT macro (a declaration) in all the functions that
* access MY_CXT.
