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” - or a unique abbreviation of one.

       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 does not contain a
       valid join style or an abbreviation of one of these names, then an error message is stored in interpreter
       interp's 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 is not a legal join style, then
       “unknown join style” is returned.
