C SPECIFICATION
void glXQueryDrawable( Display *dpy,
GLXDrawable draw,
int attribute,
unsigned int *value )
PARAMETERS
dpy Specifies the connection to the X server.
draw Specifies the GLX drawable to be queried.
attribute Specifies the attribute to be returned.
value Returns the requested value.
DESCRIPTIONglXQueryDrawable sets value to the attribute value for draw.
attribute is one of the following:
GLX_WIDTH Width of draw.
GLX_HEIGHT Height of draw.
GLX_PRESERVED_CONTENTS
True if the contents of GLXPbuffer are preserved
when a resource conflict occurs; False otherwise.
GLX_LARGEST_PBUFFER Set when the GLX pixel buffer is created by calling
glXCreatePbuffer. When False, glXCreatePbuffer
fails if it cannot allocate a GLX pixel buffer of
size width by height. When True, a pixel buffer
with the largest width and height possible (but not
larger than the values specified) is created when
the allocation of the buffer would otherwise fail.
GLX_FBCONFIG_ID XID for draw.
If draw is a GLXWindow or GLXPixmap and attribute is set to
GLX_PRESERVED_CONTENTS or GLX_LARGEST_PBUFFER, the
contents of value are undefined. If attribute is
not one of the attributes listed above, the
contents of value are undefined.
