SYNOPSIS
#include <stdint.h>
#include <stdbool.h>
#include <ldns/ldns.h>
size_t ldns_buffer_remaining_at(ldns_buffer *buffer, size_t at);
size_t ldns_buffer_remaining(ldns_buffer *buffer);
int ldns_buffer_available_at(ldns_buffer *buffer, size_t at, size_t count);
int ldns_buffer_available(ldns_buffer *buffer, size_t count);
ldns_status ldns_buffer_status(ldns_buffer *buffer);
bool ldns_buffer_status_ok(ldns_buffer *buffer);
DESCRIPTION
ldns_buffer_remaining_at() returns the number of bytes remaining between the indicated position and the limit.
buffer: the buffer
at: indicated position
Returns number of bytes
ldns_buffer_remaining() returns the number of bytes remaining between the buffer's position and limit.
buffer: the buffer
Returns the number of bytes
ldns_buffer_available_at() checks if the buffer has at least COUNT more bytes available. Before reading or writing the caller needs to

count: how much is available
Returns true or false (as int?)
ldns_buffer_status() returns the status of the buffer param[in] buffer
Returns the status
ldns_buffer_status_ok() returns true if the status of the buffer is LDNS_STATUS_OK, false otherwise
