The loggers are unique to the class in which they are called, and we pass it the name to identify where the log message originates from. For a GNU Radio block, we use 'alias()' for this value, and this is set up for us automatically in gr::block.

GR_RUNTIME_API void gr::logger_set_level	(	logger_ptr	logger,
		log4cpp::Priority::Value	level
	)

Set the logger's output level.

Sets the level of the logger. This takes the actual Log4cpp::Priority data type, which can be:

log4cpp::Priority::NOTSET
log4cpp::Priority::DEBUG
log4cpp::Priority::INFO
log4cpp::Priority::NOTICE
log4cpp::Priority::WARN
log4cpp::Priority::ERROR
log4cpp::Priority::CRIT
log4cpp::Priority::ALERT
log4cpp::Priority::FATAL
log4cpp::Priority::EMERG

Parameters

logger	the logger to set the level of.
level	new logger level of type Log4cpp::Priority

◆ major_version()

GR_RUNTIME_API const std::string gr::major_version ( )

return just the major version defined by cmake

◆ make_block_detail()

GR_RUNTIME_API block_detail_sptr gr::make_block_detail	(	unsigned int	ninputs,
		unsigned int	noutputs
	)

◆ make_buffer()

GR_RUNTIME_API buffer_sptr gr::make_buffer	(	int	nitems,
		size_t	sizeof_item,
		block_sptr	link = `block_sptr()`
	)

Allocate a buffer that holds at least nitems of size sizeof_item.

The total size of the buffer will be rounded up to a system dependent boundary. This is typically the system page size, but under MS windows is 64KB.

Parameters

nitems	is the minimum number of items the buffer will hold.
sizeof_item	is the size of an item in bytes.
link	is the block that writes to this buffer.
