Details
The attribute value is a string that specifies the file attributes that
should be gathered. It is not an error if it's not possible to read a particular
requested attribute from a file - it just won't be set. attribute should
be a comma-separated list of attribute or attribute wildcards. The wildcard "*"
means all attributes, and a wildcard like "standard::*" means all attributes in the standard
namespace. An example attribute query be "standard::*,owner::user".
The standard attributes are available as defines, like G_FILE_ATTRIBUTE_STANDARD_NAME.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
For symlinks, normally the information about the target of the
symlink is returned, rather than information about the symlink itself.
However if you pass G_FILE_QUERY_INFO_NOFOLLOW_SYMLINKS in flags the
information about the symlink itself will be returned. Also, for symlinks
that point to non-existing files the information about the symlink itself
will be returned.
If the file does not exist, the G_IO_ERROR_NOT_FOUND error will be returned.
Other errors are possible too, and depend on what kind of filesystem the file is on.
