Function Documentation

FileWriteStr()

static int FileWriteStr ( const std::string &  str, FILE *  fp  )

static

GetLogCategory()

bool GetLogCategory	(	BCLog::LogFlags &	flag,
		const std::string &	str
	)

Return true if str parses as a log category and set the flag

ListActiveLogCategories()

std::vector<CLogCategoryActive> ListActiveLogCategories

(

)

Returns a vector of the active log categories.

ListLogCategories()

std::string ListLogCategories

(

)

Returns a string with the log categories.

LogInstance()

BCLog::Logger& LogInstance

(

)

NOTE: the logger instances is leaked on exit. This is ugly, but will be cleaned up by the OS/libc. Defining a logger as a global object doesn't work since the order of destruction of static/global objects is undefined. Consider if the logger gets destroyed, and then some later destructor calls LogPrintf, maybe indirectly, and you get a core dump at shutdown trying to access the logger. When the shutdown sequence is fully audited and tested, explicit destruction of these objects can be implemented by changing this from a raw pointer to a std::unique_ptr. Since the destructor is never called, the logger and all its members must have a trivial destructor.

This method of initialization was originally introduced in ee3374234c60aba2cc4c5cd5cac1c0aefc2d817c.
