Description Vincent Untz 2007-05-12 20:29:42 UTC 
g_file_set_contents() first creates a %s.XXXXXX filename. This adds 7 characters to the filename that will be written, and it can cause the write to file because it the filename passed by the user has a size of NAME_MAX (and thus the temp filename is longer than NAME_MAX).

So the length of ".XXXXXX" needs to be taken into account by the caller. We're not supposed to know that it's 7, so having a #define for this would be great.
Comment 1 Matthias Clasen 2007-05-17 16:53:18 UTC 
I'd accept a patch to make g_file_set_contents() shorten the name as necessary
when creating the temporary name. But I don't think that the number 7 is a big secret, and I wouldn't hestitate using that knowledge if I were you.
