Parameters

instr Instruction whose op1 is the value to push.

Execute the REALLOC instruction.

Resizes the memory block pointed to by the destination variable. Operands: dest (pointer var), elemSize, count. Zero-initialises any newly allocated bytes beyond the old allocation. A count of zero frees the block.

Resizes the heap block of a pointer variable using C realloc(). Operands: op1 = destination ptr variable, op2 = element size, op3 = new element count. Zero-fills newly allocated bytes. A count of zero frees the block.
