Function Documentation

gr_buffer_reader_sptr gr_buffer_add_reader (  gr_buffer_sptr  buf, int  history )

create a new gr_buffer_reader and attach it to buffer buf

long gr_buffer_ncurrently_allocated (   )

returns # of gr_buffers currently allocated

long gr_buffer_reader_ncurrently_allocated (   )

returns # of gr_buffer_readers currently allocated

gr_buffer_sptr gr_make_buffer (  int  nitems, size_t  sizeof_item )

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.
