Memory Management Routines
These API routines allow you to manipulate and allocate memory for your API functions.
_Alloca( ) API Library Routine
Allocates a block of stack space for the calling routine. Memory is automatically freed when the routine exits._AllocHand( ) API Library Routine
Returns a new MHANDLE of size hsize. A value of zero is returned when there is insufficient memory to fulfill the request. Memory allocated with _AllocHand( ) isn't initialized._FreeHand( ) API Library Routine
Releases an MHANDLE previously allocated by means such as _AllocHand( )._GetHandSize( ) API Library Routine
Returns the usable number of bytes associated with an MHANDLE._HandToPtr( ) API Library Routine
Translates an MHANDLE to a FAR (32-bit) pointer, which points to the memory allocated to this MHANDLE._HLock( ) API Library Routine
Locks an MHANDLE to prevent it from moving if Visual FoxPro requires memory reorganization._HUnLock( ) API Library Routine
Unlocks an MHANDLE, allowing it to participate in Visual FoxPro memory reorganization._MemAvail( ) API Library Routine
Returns True if a request to allocate a handle of size bytes will succeed. Otherwise, _MemAvail( ) returns False._MemCmp( ) API Library Routine
Compares two length byte memory areas._MemFill( ) API Library Routine
Fills an area of memory starting at the location pointed to by ptr with length copies of the byte in character._MemMove( ) API Library Routine
Copies length bytes from src to dest._SetHandSize( ) API Library Routine
Changes the amount of memory allocated to an MHANDLE. The routine returns True if the reallocation is successful or False if the reallocation fails.
