/* RFC 3659 4.1.
The syntax of the SIZE command is:
size = "Size" SP pathname CRLF
The server-PI will respond to the SIZE command with a 213 reply
giving the transfer size of the file whose pathname was supplied, or
an error response if the file does not exist, the size is
unavailable, or some other error has occurred. The value returned is
in a format suitable for use with the RESTART (REST) command for mode
STREAM, provided the transfer mode and type are not altered.
size-response = "213" SP 1*DIGIT CRLF /
error-response
Note that when the 213 response is issued, that is, when there is no
error, the format MUST be exactly as specified. Multi-line responses
are not permitted.
