DESCRIPTIONldns_buffer
implementation of buffers to ease operations
ldns_buffers can contain arbitrary information, per octet. You
can write
to the current end of a buffer, read from the current position,
and
access any data within it.
Example use of buffers is in the source code of \ref host2str.c
struct ldns_struct_buffer
{
The current position used for reading/writing:
size_t _position;
The read/write limit:
size_t _limit;
The amount of data the buffer can contain:
size_t _capacity;
The data contained in the buffer:
uint8_t *_data;
If the buffer is fixed it cannot be resized:
unsigned _fixed : 1;
/** The current state of the buffer. If writing to the buf‐
fer fails
* for any reason, this value is changed. This way, you can
perform
* multiple writes in sequence and check for success after‐
wards. */
ldns_status _status;
};
