ARGUMENTS
display Specifies the connection to the X server.
count_return
Returns the number of pixmap formats that are supported by
the display.
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 scan‐
line 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;
