Classes
class	gr_basic_block
	The abstract base class for all signal processing blocks.Basic blocks are the bare abstraction of an entity that has a name, a set of inputs and outputs, and a message queue. These are never instantiated directly; rather, this is the abstract parent class of both gr_hier_block, which is a recursive container, and gr_block, which implements actual signal processing functions.

class	gr_block_detail
	Implementation details to support the signal processing abstractionThis class contains implementation detail that should be "out of sight" of almost all users of GNU Radio. This decoupling also means that we can make changes to the guts without having to recompile everything. More...
class	gr_block_executor
	Manage the execution of a single block. More...
class	gr_buffer
	Single writer, multiple reader fifo. More...
class	gr_buffer_reader
	How we keep track of the readers of a gr_buffer. More...
class	gr_dispatcher
	invoke callbacks based on select. More...
class	gr_flat_flowgraph
	Class specializing gr_flat_flowgraph that has all nodes as gr_blocks, with no hierarchy. More...
class	gr_endpoint
	Class representing a specific input or output graph endpoint. More...
class	gr_flowgraph
	Class representing a directed, acyclic graph of basic blocks. More...
class	gr_hier_block2_detail
class	gr_local_sighandler
	Get and set signal handler. More...
class	gr_single_threaded_scheduler
	Simple scheduler for stream computations. More...
class	gr_top_block_impl
	Abstract implementation details of gr_top_blockThe actual implementation of gr_top_block. Separate class allows decoupling of changes from dependent classes. More...
class	gr_vmcircbuf
	abstract class to implement doubly mapped virtual memory circular buffers More...
class	gr_vmcircbuf_createfilemapping
	concrete class to implement circular buffers with mmap and shm_open More...
class	gr_vmcircbuf_mmap_shm_open
	concrete class to implement circular buffers with mmap and shm_open More...
class	gr_vmcircbuf_mmap_tmpfile
	concrete class to implement circular buffers with mmap and shm_open More...
class	gr_vmcircbuf_sysv_shm

gr_io_signature_sptr gr_make_io_signature	(	int	min_streams,
		int	max_streams,
		int	sizeof_stream_item
	)

Create an i/o signature.

Parameters:

min_streams	specify minimum number of streams (>= 0)
max_streams	specify maximum number of streams (>= min_streams or -1 -> infinite)
