GLib Concepts

Differences between OSS and Symbian GLib
GLib Event Loop
The GLib event loop manages all the sources of an event available for GLib. These events can come from different kinds of sources like file descriptors (plain file descriptors, sockets, or pipes), time-outs, or any kind of source that can be added.
Introduction to libgmodule
libgmodule has APIs that provide a portable method for dynamically loading 'plug-ins' or, in other words, DLLs. Any program that wants to dynamically load modules must be linked to libgmodule.
Introduction to GLib Low Memory Handler
The default behavior of GLib in Linux is such that in case of a memory allocation failure, the GLib memory allocation API will call abort and hence terminate the application.
UHEAP Markers and Panics in GLib-based Applications
The 2.10.x version of GLib has introduced a new type of memory allocator called slice allocator. These allocators allocate memory in page sizes even for a small request of something like 20 bytes. Once a huge chunk has been allocated, all the future memory requests are granted using the chunk that was allocated for the first memory request. Once the free pool runs out, another huge chunk is allocated.
