Error codes are negative numbers, defined in "libisofs.h" header. An
error code is associated with a given severity, either "DEBUG", "UPDATE",

First of all, most libisofs functions return an integer. If such integer is
a negative number, it means the function has returned an error. The error code
and its severity is encoded in the return value (take a look at

Additionally, libisofs reports most of its errors in a message queue. Error
messages on that queue can be printed directly to stderr or programmatically
