Member Function Documentation

bool gr_file_source::seek	(	long	seek_point,
		int	whence
	)

seek file to seek_point relative to whence

Parameters:

seek_point	sample offset in file
whence	one of SEEK_SET, SEEK_CUR, SEEK_END (man fseek)

int gr_file_source::work	(	int	noutput_items,
		gr_vector_const_void_star &	input_items,
		gr_vector_void_star &	output_items
	)		[virtual]

just like gr_block::general_work, only this arranges to call consume_each for you

The user must override work to define the signal processing code

Implements gr_sync_block.
