| |
Coccinnelle reports a warning Warning: Use scnprintf or sprintf Adding to that, there has been a slow migration from snprintf to scnprintf. This LWN article explains the rationale for this change https: //lwn.net/Articles/69419/ Ie. snprintf() returns what *would* be the resulting length, while scnprintf() returns the actual length.
