# logging facility source files
|
|
|
|
The oai logging facility is implemented in two source files, located in [common/utils/LOG](LOG)
|
|
1. [log.c](../log.c) contains logging implementation
|
|
1. [log.h](../log.h) is the logging facility include file containing both private and public data type definitions. It also contain API prototypes.
|
|
|
|
The logging facility doesn't create any thread, all api's are executed in the context of the caller. The tracing macro's `LOG_<X>` are all using the logRecord_mt function to output the messages. To keep this function thread safe it must perform a single system call to the output stream. The buffer used to build the message must be specific to the calling thread, which is today enforced by using a variable in the logRecord_mt stack.

|
|
Data used by the logging utility are defined by the `log_t` structure which is allocated at init time, when calling the `logInit` function.
