.SH DESCRIPTION
.HP
\fIldns_buffer_remaining_at\fR()
returns the number of bytes remaining between the indicated position and
the limit.
\.br
\fBbuffer\fR: the buffer
\.br
\fBat\fR: indicated position
\.br
Returns number of bytes
.PP
.HP
\fIldns_buffer_remaining\fR()
returns the number of bytes remaining between the buffer's position and
limit.
\.br
\fBbuffer\fR: the buffer
\.br
Returns the number of bytes
.PP
.HP
\fIldns_buffer_available_at\fR()
checks if the buffer has at least \%COUNT more bytes available.
Before reading or writing the caller needs to ensure enough space
is available!
\.br
\fBbuffer\fR: the buffer
\.br
\fBat\fR: indicated position
\.br
\fBcount\fR: how much is available
\.br
Returns true or false (as int?)
.PP
.HP
\fIldns_buffer_available\fR()
checks if the buffer has count bytes available at the current position
\.br
\fBbuffer\fR: the buffer
\.br
\fBcount\fR: how much is available
\.br
Returns true or false (as int?)
.PP
.HP
\fIldns_buffer_status\fR()
returns the status of the buffer
\\param[in] buffer
\.br
Returns the status
.PP
.HP
\fIldns_buffer_status_ok\fR()
returns true if the status of the buffer is \%LDNS_STATUS_OK, false otherwise
\.br
\fBbuffer\fR: the buffer
\.br
Returns true or false
