Function rust_htslib::htslib::bgzf_raw_read

pub unsafe extern "C" fn bgzf_raw_read(
    fp: *mut BGZF, 
    data: *mut c_void, 
    length: usize
) -> isize

Read up to length bytes directly from the underlying stream without decompressing. Bypasses BGZF blocking, so must be used with care in specialised circumstances only.

@param fp BGZF file handler @param data data array to read into @param length number of raw bytes to read @return number of bytes actually read; 0 on end-of-file and -1 on error
