XDrawString(3) XLIB FUNCTIONS XDrawString(3)
NAME
XDrawString, XDrawString16 - draw text characters
SYNTAX
int XDrawString(Display *
display, Drawable
d, GC
gc, int
x, int
y,
_Xconst char *
string, int
length);
int XDrawString16(Display *
display, Drawable
d, GC
gc, int
x, int
y,
_Xconst XChar2b *
string, int
length);
ARGUMENTS
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.
x y Specify the x and y coordinates, which are relative to the
origin of the specified drawable and define the origin of
the first character.
DESCRIPTION
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.
XDrawString and
XDrawString16 can generate
BadDrawable,
BadGC, and
BadMatch errors.
DIAGNOSTICS
BadDrawable 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.
