h3. Logging Service API
This is about sending log messages via the Diag interface.
|_.Function|_.Purpose|
|log_alloc(u16 code, len)|Allocate a buffer + fill header|
|log_shorten(ptr, len)|Shorten the length of a previously allocated buffer|
|log_commit(ptr)|Send the log to diag|
|log_free(ptr)|Free a buffer previously allocated with log_alloc()|
|log_submit(ptr)|Convenience wrapper around log_alloc()/memcpy()/log_commit()|
h3. Diag Consumer Interface
This seems to be about implementing a program that consumes Diag events. You can register to certain events/masks and then receive the related information in call-backs.
