ARGUMENTS
display
Specifies the connection to the X server.
count_return
Returns the number of .
screen_number
Specifies the appropriate screen number on the host server.
DESCRIPTION
The
function returns an array of
structures that describe the types of Z format images supported
by the specified display.
If insufficient memory is available,
returns NULL.
To free the allocated storage for the
structures, use
The
macro specifies the required byte order for images for each scanline unit in
XY format (bitmap) or for each pixel value in Z format.
The
macro returns
or
to indicate whether the leftmost bit in the bitmap as displayed
on the screen is the least or most significant bit in the unit.
The
macro returns the number of bits that each scanline must be padded.
The
macro returns the size of a bitmap's scanline unit in bits.
The
macro returns the height of the specified screen in pixels.
The
macro returns the height of the specified screen in millimeters.
The
macro returns the width of the screen in pixels.
The
macro returns the width of the specified screen in millimeters.
STRUCTURES
The
structure provides an interface to the pixmap format information
that is returned at the time of a connection setup.
It contains:
typedef struct {
int depth;
int bits_per_pixel;
int scanline_pad;
} XPixmapFormatValues;
