Description:

The _smalloc() function allocates space for an object of size bytes. Nothing is allocated when the size argument has a value of zero.

Note: This function allocates memory in blocks of _amblksiz bytes; _amblksiz is a global variable defined in <stdlib.h>.

You must use _sfree() to deallocate the memory allocated by _smalloc().
