-.SH DESCRIPTION
-.PP
-.PP
-.ZN XShmQueryExtension
-checks to see if the shared memory extensions are available for the
-specified display.
-.PP
-.ZN XShmQueryVersion
-returns the version numbers of the extension implementation. Shared
-memory pixmaps are supported if the pixmaps argument returns true.
-.PP
-.ZN XShmAttach
-tells the server to attach to your shared memory segment. If all goes
-well, you will get a non-zero status, back and your XImage is ready
-for use.
-.PP
-.ZN XShmDetach
-tells the server to detach from your shared memory segment.
-.PP
-.ZN XShmPutImage
-combines an image in memory with a shape of the specified drawable. If
-XYBitmap format is used, the depth must be one, or a ``BadMatch''
-error results. The foreground pixel in the GC defines the source for
-the one bits in the image, and the background pixel defines the source
-for the zero bits. For XYPixmap and ZPixmap, the depth must match the
-depth of the drawable, or a ``BadMatch'' error results.
-.PP
-.ZN XShmGetImage
-reads image data into a shared memory XImage where display is the
-display of interest, drawable is the source drawable, image is the
-destination XImage, x and y are offsets within the drawable, and
-plane_mask defines which planes are to be read.
-.PP
-.ZN XShmCreateImage
-allocates the memory needed for an XImage structure for the specified
-display but does not allocate space for the image itself.
-.PP
-.ZN XShmPixmapFormat
-gets the format for the server. If your application can deal with the
-server pixmap data format, a shared memory segment and shminfo
-structure are created.
-.PP
-.ZN XShmCreatePixmap
-points to a pixmap which you can manipulate in all of the usual ways,
-with the added bonus of being able to edit its contents directly
-through the shared memory segment.
-.PP
-.ZN XShmGetEventBase
-gets the completion event value.

Shared +memory pixmaps are supported if the pixmaps argument returns true. +.PP +.ZN XShmAttach +tells the server to attach to your shared memory segment. If all goes +well, you will get a non-zero status, back and your XImage is ready +for use. +.PP +.ZN XShmDetach +tells the server to detach from your shared memory segment. +.PP +.ZN XShmPutImage +combines an image in memory with a shape of the specified drawable. If +XYBitmap format is used, the depth must be one, or a ``BadMatch'' +error results. The foreground pixel in the GC defines the source for +the one bits in the image, and the background pixel defines the source +for the zero bits. For XYPixmap and ZPixmap, the depth must match the +depth of the drawable, or a ``BadMatch'' error results. +.PP +.ZN XShmGetImage +reads image data into a shared memory XImage where display is the +display of interest, drawable is the source drawable, image is the +destination XImage, x and y are offsets within the drawable, and +plane_mask defines which planes are to be read. +.PP +.ZN XShmCreateImage +allocates the memory needed for an XImage structure for the specified +display but does not allocate space for the image itself. +.PP +.ZN XShmPixmapFormat +gets the format for the server. If your application can deal with the +server pixmap data format, a shared memory segment and shminfo +structure are created. +.PP +.ZN XShmCreatePixmap +points to a pixmap which you can manipulate in all of the usual ways, +with the added bonus of being able to edit its contents directly +through the shared memory segment. +.PP +.ZN XShmGetEventBase +gets the completion event value. +.PP +.SH SEE ALSO +\fIMIT-SHM - The MIT Shared Memory Extension \fP diff --git a/libXext/src/XShm.c b/libXext/src/XShm.c index cffd30756..d1f1a4d7f 100644 --- a/libXext/src/XShm.c +++ b/libXext/src/XShm.c @@ -1,431 +1,431 @@ -/*
