make2()

static sptr gr::io_signature::make2 ( int  min_streams, int  max_streams, int  sizeof_stream_item1, int  sizeof_stream_item2, buffer_type  buftype1 = default_buftype::type, buffer_type  buftype2 = default_buftype::type  )

static

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)
sizeof_stream_item1	specify the size of the items in the first stream
sizeof_stream_item2	specify the size of the items in the second and subsequent streams
buftype1	type of buffers the first stream should use (defaults to standard host double mapped buffer)
buftype2	type of buffers the second and subsequent streams should use (defaults to standard host double mapped buffer)

make3()

static sptr gr::io_signature::make3 ( int  min_streams, int  max_streams, int  sizeof_stream_item1, int  sizeof_stream_item2, int  sizeof_stream_item3, buffer_type  buftype1 = default_buftype::type, buffer_type  buftype2 = default_buftype::type, buffer_type  buftype3 = default_buftype::type  )

static

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)
sizeof_stream_item1	specify the size of the items in the first stream
sizeof_stream_item2	specify the size of the items in the second stream
sizeof_stream_item3	specify the size of the items in the third and subsequent streams
buftype1	type of buffers the first stream should use (defaults to standard host double mapped buffer)
buftype2	type of buffers the second stream should use (defaults to standard host double mapped buffer)
buftype3	type of buffers the third and subsequent streams should use (defaults to standard host double mapped buffer)

makev() [1/2]

static sptr gr::io_signature::makev ( int  min_streams, int  max_streams, const std::vector< int > &  sizeof_stream_items  )

static

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)
sizeof_stream_items	specify the size of the items in the streams

If there are more streams than there are entries in sizeof_stream_items, the value of the last entry in sizeof_stream_items is used for the missing values. sizeof_stream_items must contain at least 1 entry.

makev() [2/2]

static sptr gr::io_signature::makev ( int  min_streams, int  max_streams, const std::vector< int > &  sizeof_stream_items, const gr_vector_buffer_type &  buftypes  )

static

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)
sizeof_stream_items	specify the size of the items in the streams
buftypes	the type of buffer each stream will should use

If there are more streams than there are entries in sizeof_stream_items, the value of the last entry in sizeof_stream_items is used for the missing values. sizeof_stream_items must contain at least 1 entry.
