Yes, but declare filename as an array of char or else malloc the
memory you need. Declaring a pointer an then just writing to it
doesn't seem to be a good idea.

I would suggest:

char filename[FILENAME_MAX];

because FILENAME_MAX is defined by ANSI-C to be the maximum length
needed to store the name of a file.
