# stackalloc

Purpose
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
XPRM_MEM_NULL | Instead of exiting the process, the value NULL is returned if memory cannot be allocated

Return value
A pointer to the allocated memory or NULL in case of error
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).
