MQX 3.6 - MFS valid filename characters

ARQuattr — Wed, 13 Nov 2013 17:24:58 GMT

I'm using MFS with the USB stack in MQX 3.6 and am having trouble with certain filenames. In particular, I'm having trouble with a file that includes an apostrophe in the filename. When I call this:

ioctl(fs_ptr, IO_IOCTL_FIND_NEXT_FILE, (uint_32_ptr) &search_data);

it finds the file no problem, but when I then try to open the file using:

fopen(search_data.NAME,"r");

it fails to open the file.

As I understand it the MFS uses the standard 8.3 DOS format but I believe apostrophes are allowed. Other characters seem fine; these all work: ! @ # $ % ^ ( ) _

Are there some special restrictions with MQX MFS on allowable filename characters?

Thanks
