Maybe you should use #include <string.h> instead.

To my surprise it turns out that strdup() is not POSIX and compiler is flagged for POSIX.. hence even when I included string.h there was no prototype for strdup(). I didn't want to remove POSIX compliance because I didn't know what platforms this code is being used on.. so I replaced my strdup with malloc+strcpy. This line of code is a leftover, I will remove it.

The patch a2aad50 is very big and mix different changes. Maybe you could split the patch in small & independent changes? |

Yes I'm sorry about the size of the last commit. The problem was that I didn't know all the work I was going to do until I started doing it. I thought that the change to ifdnfc-activate was going to be much smaller.. I ended up touching almost every line.. also did not anticipate all the other problems (memory handling issues etc) that I found along the way. It was not done in any sort of order but fixed as I went along sometimes multiple iterations of fixes.. making change 1, not working because need change 2, then need 3.. finally able to test change 1 and find out that it needs some more work.. so change again.. and so on until everything works smoothly. That this was all on Raspberry pi didn't help. So I would have to basically start over to get it into separate commits. Right now I'm under a lot of work pressure and so if you would consider the patch without splitting that would be really helpful. Otherwise it will be some time before I can do it. I will take care of the comments and the few small cleanups in the next day or two. Thanks! |
This is the code which I posted about on the pcsclite-muscle mailing list. It allows ifdnfc to support multiple serial devices including startup without human intervention.
