I'm doing a simple file download and have it working fine, except that I

This problem seems to be entirely within your program and C programming, and
isn't really a libcurl issue...
This works fine, but if I want to instead assign a variable value to the
filename, it doesn't work. I've tried various ways of getting a variable
string into the filename of the struct FtpFile and am obviously missing
something simple:
char categoryName[32];
int categoryNumber;
char buffer[128];
sprintf(buffer, "%s_%d.zip", categoryName, categoryNumber);
ftpfile.filename = buffer;
This should work, assuming that buffer is still around when you want to read
out the file name. And beware of buffer overflow.
strcpy(ftpfile.filename, buffer)
That's probably not what you want.
A related question is how do I download a file using it's existing filename?
Well, you give libcurl the full URL so surely you know the filename?
The requested filename in the URL call allows me to use variable names, so
is there an option to simply save the file locally using the same name
without having to specify the name directly, which is what's causing my
problem above?
No, there's no such magic option.
