DESCRIPTION

31       ldns_buffer_remaining_at() returns the number of bytes remaining
32              between the indicated position and the limit.
33              buffer: the buffer
34              at: indicated position
35              Returns number of bytes
36
37       ldns_buffer_remaining() returns the number of bytes remaining between
38              the buffer's position and limit.
39              buffer: the buffer
40              Returns the number of bytes
41
42       ldns_buffer_available_at() checks if the buffer has at least COUNT more
43              bytes available.  Before reading or writing the caller needs to
44              ensure enough space is available!
45              buffer: the buffer
46              at: indicated position
47              count: how much is available
48              Returns true or false (as int?)
49
50       ldns_buffer_available() checks if the buffer has count bytes available
51              at the current position
52              buffer: the buffer
53              count: how much is available
54              Returns true or false (as int?)
55
56       ldns_buffer_status() returns the status of the buffer \param[in] buffer
57              Returns the status
58
59       ldns_buffer_status_ok() returns true if the status of the buffer is
60              LDNS_STATUS_OK, false otherwise
61              buffer: the buffer
62              Returns true or false
