Perhaps these string_upper and string_lower utility functions
should return dst not void so these functions could be used in
output calls.
So instead of:
+ string_upper(prefix_name, prefix_name);
snprintf(name, sizeof(name), "%s-%s", prefix_name, kind);
this could be consolidated:
snprintf(name, sizeof(name), "%s-%s", string_upper(prefix_name), kind);
Perhaps:
