naEnumgetFileType

NaEnumGetFileType is a function that retrieves the file type of a given file. It is commonly used in the Nautilus file manager, a part of the GNOME desktop environment, to determine the type of a file based on its magic number.

The magic number is a unique sequence of bytes that is stored at the beginning of a file. It serves as a signature that identifies the file type. NaEnumGetFileType uses this magic number to determine the file type and return a corresponding enum value.

The function takes two parameters: the file path to be examined and a pointer to a GtkWidget that is used to display the file type. The function returns a GType, which is the type of the file, and a gboolean indicating whether the file type was successfully determined.

NaEnumGetFileType is often used in combination with other functions, such as NautilusFileScaleInputStream, to provide additional information about the file, such as its size or metadata. The function is also used in various Nautilus plugins and extensions.

The magic numbers used by NaEnumGetFileType are based on the list of magic numbers stored in the "magic" database. This database is used to store the unique sequences of bytes that identify different file types.

Overall, NaEnumGetFileType provides a convenient way to determine the type of a file in Nautilus, making it easier to manage and organize files based on their type. The function is a key component of the Nautilus file manager, and its usage is extensive throughout the GNOME desktop environment.
