6.19 Memory Management and Garbage Collection

Guile uses a garbage collector to manage most of its objects. While the garbage collector is designed to be mostly invisible, you sometimes need to interact with it explicitly.

See Garbage Collection for a general discussion of how garbage collection relates to using Guile from C.
