+.SH NAME
+XCURSOR \- Cursor management library
+
+.SH SYNOPSIS
+.nf
+.B #include <X11/Xcursor/Xcursor.h>
+.fi
+.SH DESCRIPTION
+.B Xcursor
+is a simple library designed to help locate and load cursors. Cursors can
+be loaded from files or memory. A library of common cursors exists which
+map to the standard X cursor names. Cursors can exist in several sizes and
+the library automatically picks the best size.
+
+.SH FUNCTIONAL OVERVIEW
+Xcursor is built in a couple of layers; at the bottom layer is code which
+can load cursor images from files. Above that is a layer which locates
+cursor files based on the library path and theme. At the top is a layer
+which builds cursors either out of an image loaded from a file or one of the
+standard X cursors. When using images loaded from files, Xcursor prefers
+to use the Render extension CreateCursor request if supported by the X
+server. Where not supported, Xcursor maps the cursor image to a standard X
+cursor and uses the core CreateCursor request.
+
+.SS CURSOR FILES
+Xcursor defines a new format for cursors on disk. Each file holds
+one or more cursor images. Each cursor image is tagged with a nominal size
+so that the best size can be selected automatically. Multiple cursors of
+the same nominal size can be loaded together; applications are expected to
+use them as an animated sequence.
+.P
+Cursor files are stored as a header containing a table of contents followed
+by a sequence of chunks. The table of contents indicates the type, subtype
+and position in the file of each chunk. The file header looks like:
+.LP
+.in +.2i
+\fImagic\fP\^: CARD32 'Xcur' (0x58, 0x63, 0x75, 0x72)
+.br
+\fIheader\fP\^: CARD32 bytes in this header
+.br
+\fIversion\fP\^: CARD32 file version number
+.br
+\fIntoc\fP\^: CARD32 number of toc entries
+\fItoc\fP\^: LISTofTOC table of contents
+.in -.2i
+.P
+Each table of contents entry looks like:
+.LP
+.in +.2i
+\fItype\fP\^: CARD32 entry type
+\fIsubtype\fP\^: CARD32 type-specific label - size for images
+\fIposition\fP\^: CARD32 absolute byte position of table in file
+.in -.2i
+.P
+.P
+Each chunk in the file has set of common header fields followed by
+additional type-specific fields:
+.LP
+.in +.2i
+\fIheader\fP\^: CARD32 bytes in chunk header (including type-specific fields)
+.br
+\fItype\fP\^: CARD32 must match type in TOC for this chunk
+.br
+\fIsubtype\fP\^: CARD32 must match subtype in TOC for this chunk
+.br
+\fIversion\fP\^: CARD32 version number for this chunk type
+.in -.2i
+.P
+There are currently two chunk types defined for cursor files; comments and
+images. Comments look like:
+.LP
+.in +.2i
+\fIheader\fP\^: 20 Comment headers are 20 bytes
+.br
+\fItype\fP\^: 0xfffe0001 Comment type is 0xfffe0001
+.br
+\fIsubtype\fP\^: { 1 (COPYRIGHT), 2 (LICENSE), 3 (OTHER) }
+.br
+\fIversion\fP\^: 1
+.br
+\fIlength\fP\^: CARD32 byte length of UTF-8 string
+.br
+\fIstring\fP\^: LISTofCARD8 UTF-8 string
+.in -.2i
+.P
+Images look like:
+.LP
+.in +.2i
+\fIheader\fP\^: 36 Image headers are 36 bytes
+.br
+\fItype\fP\^: 0xfffd0002 Image type is 0xfffd0002
+.br
+\fIsubtype\fP\^: CARD32 Image subtype is the nominal size
+.br
+\fIversion\fP\^: 1
+.br
+\fIwidth\fP\^: CARD32 Must be less than or equal to 0x7fff
+.br
+\fIheight\fP\^: CARD32 Must be less than or equal to 0x7fff
+.br
+\fIxhot\fP\^: CARD32 Must be less than or equal to width
+.br
+\fIyhot\fP\^: CARD32 Must be less than or equal to height
+.br
+\fIdelay\fP\^: CARD32 Delay between animation frames in milliseconds
+.br
+\fIpixels\fP\^: LISTofCARD32 Packed ARGB format pixels
+.in -.2i
+
+.SS THEMES
+Xcursor (mostly) follows the freedesktop.org spec for theming icons. The
+default search path it uses is $HOME/.icons, /usr/share/icons,
+/usr/share/pimaps, /usr/X11R6/lib/X11/icons. Within each of these
+directorys, it searches for a directory using the theme name. Within the
+theme directory, it looks for cursor files in the 'cursors' subdirectory.
+It uses the first cursor file found along the path.
+.PP
+If necessary, Xcursor also looks for a "index.theme" file in each theme
+directory to find inherited themes and searches along the path for those
+themes as well.
+.PP
+If no theme is set, or if no cursor is found for the specified theme,
+Xcursor checks the "default" theme.
+
+.SH DATATYPES
+
+.TP
+.B XcursorImage
+holds a single cursor image in memory. Each pixel in the cursor is a 32-bit
+value containing ARGB with A in the high byte.
+.sp
+.nf
+.ft CR
+ typedef struct _XcursorImage {
+ XcursorDim size; /\(** nominal size for matching */
+ XcursorDim width; /\(** actual width */
+ XcursorDim height; /\(** actual height */
+ XcursorDim xhot; /\(** hot spot x (must be inside image) */
+ XcursorDim yhot; /\(** hot spot y (must be inside image) */
+ XcursorPixel *pixels; /\(** pointer to pixels */
+ } XcursorImage;
+.ft
+.fi
+
+.TP
+.B XcursorImages
+holds multiple XcursorImage structures. They're all freed when the
+XcursorImages is freed.
+.sp
+.nf
+.ft CR
+ typedef struct _XcursorImages {
+ int nimage; /\(** number of images */
+ XcursorImage **images; /\(** array of XcursorImage pointers */
+ } XcursorImages;
+.ft
+.fi
+
+.TP
+.B XcursorCursors
+Holds multiple Cursor objects. They're all freed when the XcursorCursors is
+freed. These are reference counted so that multiple XcursorAnimate
+structures can use the same XcursorCursors.
+.sp
+.nf
+.ft CR
+ typedef struct _XcursorCursors {
+ Display *dpy; /\(** Display holding cursors */
+ int ref; /\(** reference count */
+ int ncursor; /\(** number of cursors */
+ Cursor *cursors; /\(** array of cursors */
+ } XcursorCursors;
+.ft
+.fi
+
+.TP
+.B XcursorAnimate
+References a set of cursors and a sequence within that set. Multiple
+XcursorAnimate structures may reference the same XcursorCursors; each
+holds a reference which is removed when the XcursorAnimate is freed.
+.sp
+.nf
+.ft CR
+ typedef struct _XcursorAnimate {
+ XcursorCursors *cursors; /\(** list of cursors to use */
+ int sequence; /\(** which cursor is next */
+ } XcursorAnimate;
+.ft
+.fi
+
+.TP
+.B XcursorFile
+Xcursor provides an abstract API for accessing the file data. Xcursor
+provides a stdio implementation of this abstract API; applications
+are free to create additional implementations. These functions
+parallel the stdio functions in return value and expected argument values;
+the read and write functions flip the arguments around to match the POSIX
+versions.
+.sp
+.nf
+.ft CR
+ typedef struct _XcursorFile {
+ void *closure;
+ int (*read) (XcursorFile *file, unsigned char *buf, int len);
+ int (*write) (XcursorFile *file, unsigned char *buf, int len);

+.TQ
+XcursorImages *XcursorLibraryLoadImages (const char *name, const char *theme, int size)

+.TP
+XcursorBool XcursorSupportsARGB (Display *dpy)
+Returns whether the display supports ARGB cursors or whether cursors will be
+mapped to a core X cursor.
+
+.TP
+XcursorBool XcursorSetDefaultSize (Display *dpy, int size)
+Sets the default size for cursors on the specified display. When loading
+cursors, those who's nominal size is closest to this size will be preferred.
+
+.TP
+int XcursorGetDefaultSize (Display *dpy)
+Gets the default cursor size.
+
+.TP
+XcursorBool
+XcursorSetTheme (Display *dpy, const char *theme)
+Sets the current theme name.
+
+char *
+XcursorGetTheme (Display *dpy)

+
+.SH RESTRICTIONS
+.B Xcursor
+will probably change radically in the future; weak attempts will be made to
+retain some level of source-file compatibility.
