Allocates a certain number of bytes from the local dynamic memory pool and pushes the address (a transient pointer, type *) of the first allocated byte onto the evaluation stack.
Assembly: mscorlib (in mscorlib.dll)
The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:
Allocate space from the local heap.
The stack transitional behavior, in sequential order, is:
The number of bytes to be allocated is pushed onto the stack.
The number of bytes is popped from the stack; an amount of memory corresponding to the size is allocated from the local heap.
A pointer to the first byte of the allocated memory is pushed onto the stack.
The localloc instruction allocates size (type natural unsigned int) bytes from the local dynamic memory pool and returns the address (a transient pointer, type *) of the first allocated byte. The block of memory returned is initialized to 0 only if the initialize flag on the method is true. When the current method executes a Ret, the local memory pool is made available for reuse.
The localloc instruction cannot occur within a filter, catch, finally, or fault block.
StackOverflowException is thrown if there is insufficient memory to service the request.
The following Emit method overload can use the localloc opcode:
Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows XP SP2 x64 Edition, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
