Determine size of remote file.
#include <ftplib.h> int FtpSize(char *path, unsigned int *size, char mode, netbuf *nControl);
FtpSize() attempts to determine the size of a remote file.
If a good response is received and the size is successfully parsed out of the result, 1 is returned. Otherwise, 0 is returned.
Some servers may not support the SIZE command. If this request fails, the size may be available in the response to a RETR (FtpOpen() with typ=FTPLIB_FILE_READ).
