gFileQueryInfo(object, attributes, flags = "G_FILE_QUERY_INFO_NONE", 
    cancellable = NULL, .errwarn = TRUE)

Arguments

object

input GFile.

an attribute query string.

flags

a set of GFileQueryInfoFlags.

cancellable

optional GCancellable object, NULL to ignore.

.errwarn

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.

Value

A list containing the following elements:

retval

[GFileInfo] a GFileInfo for the given file, or NULL on error.

error

a GError.
