Allocate memory on the Mosel execution stack.
Synopsis
void *stackalloc(XPRMcontext ctx, size_t size, int flags);
Arguments
ctx 
Mosel's execution context
size 
Amount of memory to allocate in bytes
flags 
Possible values (they can be combined):
XPRM_MEM_ZERO 
The allocated memory is initialised with zeros

Further information
This function allocates a block of memory on the Mosel execution stack. This memory block must be released before the termination of the calling subroutine by a call to stackfree otherwise there is no guarantee on when the deallocation will occur (the stack is anyway released at program termination).
