XDrawString, XDrawString16 - draw text characters
XDrawString(display, d, gc, x, y, string, length)
int x, y;
XDrawString16(display, d, gc, x, y, string, length)
int x, y;
Specifies the drawable.
Specifies the connection to the X server.
Specifies the GC.
Specifies the number of characters in the string argument.
Specifies the character string.
Specify the x and y coordinates, which are relative to the
origin of the specified drawable and define the origin of the first character.
Each character image, as defined by the font in the GC, is treated as an additional mask for a fill operation on the drawable. The drawable is modified only where the font character has a bit set to 1. For fonts defined with 2-byte matrix indexing and used with XDrawString16, each byte is used as a byte2 with a byte1 of zero.
Both functions use these GC components: function, plane-mask, fill-style, font, subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask. They also use these GC mode-dependent components: foreground, background, tile, stipple, tile-stipple-x-origin, and tile-stipple-y-origin.
A value for a Drawable argument does not name a defined Window
A value for a GContext argument does not name a defined GContext.
window is used as a Drawable.
Some argument or pair of arguments has the correct type and
range but fails to match in some other way required by the request.
