 NAME

      styles

 SYNOPSIS
      #include <tk.h>

      int
      Tk_GetCapStyle(interp, string, capPtr)

      char *
      Tk_NameOfCapStyle(cap)

 ARGUMENTS
      Tcl_Interp   *interp   (in)       Interpreter   to   use   for   error
                                       reporting.

      char         *string   (in)      String containing name of cap  style:
                                       one  of ```butt'', ``projecting'', or
                                       ``round''.

      int          *capPtr   (out)     Pointer to location in which to store
                                       X cap style corresponding to string.

      int          cap       (in)        Cap   style:   one   of    CapButt,
                                       CapProjecting, or CapRound.

 DESCRIPTION
      Tk_GetCapStyle places in *capPtr the  X  cap  style  corresponding  to
      string.   This  will  be  one of the values CapButt, CapProjecting, or
      CapRound.  Cap styles are typically used in  X  graphics  contexts  to
      indicate  how  the  end-points  of  lines should be capped.  See the X
      documentation for information on what each style implies.

      Under normal circumstances the return value is TCL_OK  and  interp  is
      unused.    If   string  doesn't  contain  a  valid  cap  style  or  an
      abbreviation of one of these names, then an error message is stored in
      interp->result, TCL_ERROR is returned, and *capPtr is unmodified.

      Tk_NameOfCapStyle is the logical inverse of Tk_GetCapStyle.   Given  a
      cap  style  such  as  CapButt it returns a statically-allocated string
      corresponding to cap.  If cap isn't a legal cap style, then  ``unknown
      cap style'' is returned.
