not sure if this is outside the scope of this mailing list but i
just downloaded the source for a simple SSL-aware ftp client
(netkit-ftp-ssl), did the configure and the make and got:
ftp.c: In function ârecvrequestâ:
ftp.c:1127: error: âpdataâundeclared (first use in this function)
ftp.c:1127: error: (Each undeclared identifier is reported only once
ftp.c:1127: error: for each function it appears in.)
ok, fair enough, check the offending header file to find the
following macro definition:
#define is_ssl_fd(X,Y) ( (SSL_get_fd((X))==0) || \
(SSL_get_fd((X))==1) || \
(SSL_get_fd((X))==pdata) || \
(SSL_get_fd((X))==(Y)) \
?????. so i have a macro which accepts two arguments, but expands
to include an explicit reference to something called "pdata", which
does not exist, hence the error message.
i tend to avoid defining macros that refer to anything but their own
arguments. what might the above mean? is there some well-known idiom
for C programmers that makes the above, in some way, acceptable?
(i've perused the code and the object "pdata", whatever that is, is
simply not defined anywhere. so is there a context in which the above
makes sense in some way?)
