Allocates a chunk of memory that is automatically deallocated when the object is being lost. Be aware that this method can be used to create flanging pointers.

Please keep the object around as long as the memory is used.

class library extends object

Opens a shared C library

The path must be a string denoting the location of the library in the system. The apispec may be a function that is called with the name whenever getattr(name) is called. It returns a ctype or wrap -object to indicate what the library should do.

malloc(ctype : object, count = null, clear = null)

ctype	not documented
count	not documented
clear	not documented
returns	not documented

Where the sizeof returns the size of the type, this thing returns a c-object of that size.

The c-object created with this method must be deallocated.
