DESCRIPTION

Module to export constants for MQTT protocol.

"FUNCTIONS"

"decode_remaining_length( $data, \$offset )"

Calculates the "remaining length" from the bytes in $data starting at the offset read from the scalar reference. The offset reference is subsequently incremented by the number of bytes processed.

encode_remaining_length( $length )

Calculates the "remaining length" bytes from the length, $length, and returns the packed bytes as a string.

"decode_byte( $data, \$offset )"

Returns a byte by unpacking it from $data starting at the offset read from the scalar reference. The offset reference is subsequently incremented by the number of bytes processed.

"decode_short( $data, \$offset )"

Returns a short (two bytes) by unpacking it from $data starting at the offset read from the scalar reference. The offset reference is subsequently incremented by the number of bytes processed.

"decode_string( $data, \$offset )"

Returns a string (short length followed by length bytes) by unpacking it from $data starting at the offset read from the scalar reference. The offset reference is subsequently incremented by the number of bytes processed.
