#[unsafe(no_mangle)]pub unsafe extern "C" fn xmlCatalogSetDebug(level: c_int) -> c_intExpand description
Set the catalog debug level (upstream xmlCatalogSetDebug: returns the previous level; levels <= 0 reset to 0).
§SAFETY
The function touches crate-global state only; it is safe as long as the caller respects the library’s global initialization/cleanup ordering (xmlInitParser before use, xmlCleanupParser only after all users are done).
Violating the global lifecycle ordering, or calling this after teardown or from a signal handler, is undefined behavior.
