NAME

       Tk_GetJoinStyle, Tk_NameOfJoinStyle - translate between strings and join styles

SYNOPSIS

       #include <tk.h>

       int
       Tk_GetJoinStyle(interp, string, joinPtr)

       CONST char *
       Tk_NameOfJoinStyle(join)

ARGUMENTS

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

       CONST char   *string    (in)      String  containing  name of join style: one of ``bevel'', ``miter'', or
                                         ``round''.

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

       int          join       (in)      Join style: one of JoinBevel, JoinMiter, JoinRound.

DESCRIPTION

       Tk_GetJoinStyle  places  in  *joinPtr  the  X  join  style  corresponding to string, which will be one of
       JoinBevel, JoinMiter, or JoinRound.  Join styles are typically used in X graphics  contexts  to  indicate
       how  adjacent  line  segments should be joined together.  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  join  style  or  an  abbreviation  of  one  of  these  names,  then  an error message is stored in
       interp->result, TCL_ERROR is returned, and *joinPtr is unmodified.

       Tk_NameOfJoinStyle is the logical inverse of Tk_GetJoinStyle.  Given a join style such  as  JoinBevel  it
       returns  a  statically-allocated  string  corresponding  to join.  If join isn't a legal join style, then
       ``unknown join style'' is returned.
