void CCFree (  LPVOID  Buf  )

Like malloc but does not throw exceptions. Change size of memory block, similar to realloc but does not throw exceptions. Like free. Author: Andy_Pennell (Xara Group Ltd) <camelotdev@xara.com> Date: 25/10/93 Parameters: pointer  to memory allocated with CCMalloc (or NULL) [INPUTS] None  [OUTPUTS] Returns: None Errors: None See also: CCMalloc;free Definition at line 753 of file fixmem.cpp. { #ifdef USE_CRIT CCMallocCriticalSection Cs; #endif #ifdef _OUTPUT_DEBUG if (Buf) { CCMallocList* p = (CCMallocList*) Buf; p--; TotalMalloced -= p->Size; TRACE( _T("UnMalloced %ld (-%ld in %s at %ld)\n"),TotalMalloced, p->Size, p->Filename, p->LineNum); } #endif // check magic longword (and remove it to find double-frees) Buf = CheckMagic( Buf, TRUE ); // TRACE( _T("CCFree at 0x%08x (0x%08x)\n"), Buf, ((char*)Buf - MAGIC_EXTRA)); // then free it free( Buf ); }

TunedMemory* GetTunedMemManager (   )

Finds the Tuned Memory manager so that people that need to know get ask it for memory etc. Author: Rik_Heywood (Xara Group Ltd) <camelotdev@xara.com> Date: 1/5/95 Returns: A pointer to the tuned memory manager Definition at line 794 of file fixmem.cpp. { return &TheTunedMemoryManager; }

size_t RetailCCGetBlockSize (  LPVOID  Block  )

Finds out how big a block of ram someone asked for when they called CCMalloc. Author: Rik_Heywood (Xara Group Ltd) <camelotdev@xara.com> Date: 1/5/95 Parameters: Block  - the alloc'ed block we want to know the size of [INPUTS] Returns: the size of the block that was asked for Definition at line 673 of file fixmem.cpp. { #ifdef USE_CRIT CCMallocCriticalSection Cs; #endif if (Block==NULL) return 0; #if !defined(__WXMAC__) return _msize(Block); #else return malloc_size(Block); #endif }

LPVOID RetailCCMalloc (  UINT32  Size  )

Like malloc but does not throw exceptions. LPVOID RetailCCMalloc( UINT32 size ) Author: Gerry_Iles (Xara Group Ltd) <camelotdev@xara.com> Date: 1/9/94 Parameters: size  of memory required (must be non-zero) [INPUTS] None  [OUTPUTS] Returns: Pointer to new block, or NULL if failed. Errors: None. See also: CCFree;RetailCCRealloc;malloc Definition at line 565 of file fixmem.cpp. { #ifdef USE_CRIT CCMallocCriticalSection Cs; #endif if (Size==0L) // size of 0 is illegal return NULL; if (checksize(Size)) return NULL; // if too big // save VC++s internal fail-memory pointer and reset it so nothing special occurs // if memory runs out #if !defined(__WXMAC__) _PNH old_handler = _set_new_handler( NULL ); #else new_handler pnh = set_new_handler(NULL); #endif // call malloc to get the memory or a NULL pointer void *p = malloc( (size_t)Size ); // repair the function pointer to its old value and return our pointer #if !defined(__WXMAC__) _set_new_handler( old_handler ); #else set_new_handler(pnh); #endif // set the error if it didn't work if (p == NULL) Error::SetError(_R(IDS_OUT_OF_MEMORY)); return p; }

LPVOID RetailCCRealloc (  LPVOID  Buf, UINT32  Size )

Change size of memory block, similar to realloc but does not throw exceptions. LPVOID RetailCCRealloc( LPVOID buf, UINT32 size ) Author: Gerry_Iles (Xara Group Ltd) <camelotdev@xara.com> Date: 1/9/94 Parameters: Pointer  to block allocated with CCMalloc (can be NULL) and new size (must be non-zero) [INPUTS] Returns: Pointer to new block (might have changed) or NULL if cannot reallocate (old block will remain intact) Errors: None. See also: RetailCCMalloc;CCFree;realloc Definition at line 620 of file fixmem.cpp. { #ifdef USE_CRIT CCMallocCriticalSection Cs; #endif if (Size==0L) // size of 0 is illegal return NULL; if (checksize(Size)) return NULL; // if too big // save VC++s internal fail-memory pointer and reset it so nothing special occurs // if memory runs out #if !defined(__WXMAC__) _PNH old_handler = _set_new_handler( NULL ); #else new_handler pnh = set_new_handler(NULL); #endif // call realloc void *p = realloc( Buf, (size_t)Size ); // finally repair the function pointer to its old value and return our pointer #if !defined(__WXMAC__) _set_new_handler( old_handler ); #else set_new_handler(pnh); #endif // set the error if it didn't work if (p == NULL) Error::SetError(_R(IDS_OUT_OF_MEMORY)); // return result, storing magic word return p; }
