NAME

ldns_buffer_remaining_at, ldns_buffer_remaining, ldns_buffer_available_at, ldns_buf‐ fer_available, ldns_buffer_status, ldns_buffer_status_ok - check buffer status

SYNOPSIS

#include <stdint.h> #include <stdbool.h> #include <ldns/ldns.h> size_t ldns_buffer_remaining_at(const ldns_buffer *buffer, size_t at); size_t ldns_buffer_remaining(const ldns_buffer *buffer); int ldns_buffer_available_at(const ldns_buffer *buffer, size_t at, size_t count); int ldns_buffer_available(const ldns_buffer *buffer, size_t count); ldns_status ldns_buffer_status(const ldns_buffer *buffer); bool ldns_buffer_status_ok(const 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 posi‐ tion 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 ensure enough space is available! buffer: the buffer at: indicated position count: how much is available Returns true or false (as int?) ldns_buffer_available() checks if the buffer has count bytes available at the current position buffer: the buffer 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 buffer: the buffer Returns true or false
