Function Documentation

void LOG_setup_tag

(

void

)

Set the LOG tag.

This function should be called by the startup-code, prior to any output of the loglib (if used) or the thread-creation using the thread package. If l4util_progname is empty, it will be filled with the first 8 chars of the last portion of the program name.

With L4Env, this function is called after initializing l4util's argc/argv. It is called via constructors a second time before calling main(). Without L4Env and the __main() from l4util, this function is called as constructor after initializing argc/argv.

Variable Documentation

char LOG_tag[9] = ""

Symbol defining the logtag.

This is a weak symbol which can be overwritten to define the logtag. The intention is that you can set the logtag on compile-time, if you cannot guarantee to call LOG_init() prior to first output for whatever reasons.

Use one of the two methods to define the logtag, either by defining this symbol or by calling LOG_init().

Note:

The length of the symbol must be 9 characters in length, and it must be 0-terminated.
