NAME
     strwidth, lstrwidth - returns the width of the specified text string

C SPECIFICATION
     long strwidth(str)
     String str;

     long lstrwidth(type,str)
     long type;
     void *str;

PARAMETERS
     type      expects the type of this string.  See the man page for charstr
               for a description of the type argument.

     str       expects the pointer to the string to be measured.

DESCRIPTION
     strwidth and lstrwidth return the width of a text string in pixels, using
     the character spacing parameters of the current raster font.  These
     functions are useful when doing a simple mapping from screen space to
     world space.

     Undefined characters have zero width.
