NAME

XDrawString, XDrawString16 - draw text characters

SYNTAX

XDrawString(display, d, gc, x, y, string, length)

      Display *display;

      Drawable d;

      GC gc;

      int x, y;

      char *string;

      int length;

XDrawString16(display, d, gc, x, y, string, length)

      Display *display;

      Drawable d;

      GC gc;

      int x, y;

      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. and define the origin of the first character
x
y: Specify the x and y coordinates, which are relative to the origin of the specified drawable.

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.
