Author
Peter Donovan (peter.nosp@m.dono.nosp@m.van@b.nosp@m.erke.nosp@m.ley.e.nosp@m.du) To create a new hashmap:
return address
Definition hashmap.h:74
#define CAPACITY
Definition hashmap_test.c:8
where CAPACITY is the maximum capacity of the hashmap and NOTHING is a pointer key that is guaranteed to be never used (e.g., NULL). To put an entry into the hashmap: where POINTER is a pointer not equal to NOTHING and VALUE is an integer. This will segfault if the hashmap is already at capacity.

To retrieve a value from the hashmap:

This will segfault if the entry is not in the hashmap.

See hashmap.h for documentation on how to declare other hashmap types.
