Adobe Flash C++ Compiler (FlasCC)

A complete BSD-like C/C++ development environment with a GCC based cross-compiler capable of targeting the Adobe Flash Runtime.

C/C++ API ReferenceAVM2.h

The AVM2.h header file contains various low-level FlasCC-specific utility functions and macros.

Function	Description
__avm2_apply_args	#define __avm2_apply_args() 复制代码 Returns a pointer to data describing how to perform a call with the same arguments as were passed to the current function. For more information, see http://tigcc.ticalc.org/doc/gnuexts.html#SEC67
__avm2_apply	#define __avm2_apply(function, arguments, size) 复制代码 Invokes function with a copy of the parameters described by arguments and size. For more information, see http://tigcc.ticalc.org/doc/gnuexts.html#SEC67 Parameters: function - The function to be invoked. arguments - The arguments to be passed. This should be the value returned by __avm2_apply_args(). size - The number of bytes in the stack argument data.
__avm2_return	#define __avm2_return(result) 复制代码 Returns the value described by result from the containing function. Parameters: result - The value returned by __avm2_apply.
__builtin_va_arg_pack	#define __builtin_va_arg_pack 复制代码 Error. Not supported in FlasCC.
__builtin_va_arg_pack_len	#define __builtin_va_arg_pack_len 复制代码 Error. Not supported in FlasCC.

avm2_locked_id	unsigned avm2_locked_id(unsigned *mtx); 复制代码 Returns the id of the lock owner. Low-level concurrency primitives -- expect hangs or worse if not used properly. Non-recursive mutexes. Parameters: mtx - ID of lock owner or 0.
avm2_lock	void avm2_lock(unsigned *mtx); 复制代码 Low-level concurrency primitives -- expect hangs or worse if not used properly. Non-recursive mutexes. Parameters: mtx - lock with thread id.
avm2_lock_id	void avm2_lock_id(unsigned *mtx, unsigned id); 复制代码 Low-level concurrency primitives -- expect hangs or worse if not used properly. Non-recursive mutexes. Parameters: mtx - lock with any non-0 value. id - lock owner id.
avm2_unlock	void avm2_unlock(unsigned *mtx); 复制代码 Super low-level concurrency primitives -- expect hangs or worse if not used properly. Non-recursive mutexes. Parameters: mtx - unlock.
Address token-based conditions
avm2_msleep	int avm2_msleep(void *addr, unsigned *mtx, int timo); 复制代码 Waits for addr to be woken for timo milliseconds (or forever if timo==0). Releases mutex on entry, re-acquired before return 0 on timeout, non-zero on wake. Parameters: addr - Sleep on address. mtx - Must be locked on entry. timo - Number of milliseconds this function waits for addr to be woken (forever if timo==0).
avm2_wake	int avm2_wake(void *addr); 复制代码 Wake any threads msleeping on addr, returns non-zero if a thread was woken. Parameters: addr - Address pointing to sleeping threads. Example Usage: See the 09_pthreads sample
avm2_wake_one	int avm2_wake_one(void *addr); 复制代码 Wake zero (if none msleeping on addr) or one threads msleeping on addr, returns non-zero if any thread was woken. Parameters: addr - Address pointing to sleeping threads.
avm2_thr_impersonate	void *avm2_thr_impersonate(long tid, void *(*proc)(void *), void *arg); 复制代码 Call proc(arg) while impersonating the thread specified by tid. Parameters: tid - Long containing the thread to impersonate. proc - The function pointer. arg - The data to pass to the function pointer.
avm2_ui_thunk	void *avm2_ui_thunk(void *(*proc)(void *), void *arg); 复制代码 Call proc(arg) on the UI Worker as calling thread. Parameters: proc - The function pointer. arg - The data to pass to the function pointer.
avm2_is_ui_worker	int avm2_is_ui_worker(); 复制代码 Returns non-zero if running on the UI Worker.
avm2_wait_for_ui_frame	int avm2_wait_for_ui_frame(int timo); 复制代码 Wait for a frame event or until timeout. Returns 0 on timeout. Parameters: timo - A timeout interval, in milliseconds.
avm2_self_lock	void avm2_self_lock(); 复制代码 Lock this thread to this Worker -- recursive OK.
avm2_self_unlock	void avm2_self_unlock(); 复制代码 Unlock this thread.
avm2_self_msleep	int avm2_self_msleep(void *addr, int timo); 复制代码 Works like avm2_msleep with mtx being "self" -- "self" must be locked using avm2_self_lock. Parameters: addr - Sleep on address. timo - Number of milliseconds this function waits for addr to be woken (forever if timo==0). Example Usage: See the 09_pthreads sample
avm2_tramp_alloc	void *avm2_tramp_alloc(void *funPtr, int sret, void *arg0, void *arg1); 复制代码 Trampoline support. For more information, see sdk/usr/share/avm2_tramp.cpp. Parameters: funPtr - Function pointer. sret - Size of the structure return type for POD or the negative size of the structure for non-POD. Must be zero for a non-structure return type. arg0 - First argument. arg1 - Second argument.
avm2_tramp_free	void avm2_tramp_free(void *trampFunPtr); 复制代码 Trampoline support. For more information, see sdk/usr/share/avm2_tramp.cpp. Parameters: trampFunPtr - Function pointer to be freed.
