XDrawString(3) XLIB FUNCTIONS XDrawString(3)
XDrawString, XDrawString16 - draw text characters
int XDrawString(Display *display, Drawable d, GC gc, int x, int y, char *string, int
int XDrawString16(Display *display, Drawable d, GC gc, int x, int y, XChar2b *string, int
d Specifies the drawable.
display Specifies the connection to the X server.
gc Specifies the GC.
length Specifies the number of characters in the string argument.
string Specifies the character string.
y Specify the x and y coordinates, which are relative to the origin of the speci-
fied 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 char-
acter 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-stip-
XDrawString and XDrawString16 can generate BadDrawable, BadGC, and BadMatch errors.
A value for a Drawable argument does not name a defined Window or Pixmap.
BadGC A value for a GContext argument does not name a defined GContext.
BadMatch An InputOnly window is used as a Drawable.
BadMatch Some argument or pair of arguments has the correct type and range but fails to
match in some other way required by the request.
