GFileAttributeMatchers are reference
counted structures, and are created with a reference count of 1. If
the number of references falls to 0, the GFileAttributeMatcher is
automatically destroyed.gFileAttributeMatcherNew(attributes)attributesattribute string should be formatted with specific keys separated
from namespaces with a double colon. Several "namespace::key" strings may be
concatenated with a single comma (e.g. "standard::type,standard::is-hidden").
The wildcard "*" may be used to match all keys and namespaces, or
"namespace::*" will match all keys in a given namespace.
Examples of strings to use:
| "*" |
| matches all attributes. |
| "standard::is-hidden" |
| matches only the key is-hidden in the standard namespace. |
| "standard::type,unix::*" |
| matches the type key in the standard namespace and all keys in the unix namespace. |
