Grib data seek, format of a procedure referenced in the context that is used to seek the current position in a stream

@param c : the context where the tell will apply @param offset : the offset to seek to @param whence : If whence is set to SEEK_SET, SEEK_CUR, or SEEK_END, the offset is relative to the start of the file, the current position indicator, or end-of-file, respectively. @param stream : the stream @return 0 if OK, integer value on error
