- DESCRIPTION
- Tk_GetCapStyle places in *_c_a_p_P_t_r the X cap style correspond-
- ing to _s_t_r_i_n_g. This will be one of the values CapButt, Cap-
- Projecting, 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
- _i_n_t_e_r_p is unused. If _s_t_r_i_n_g doesn't contain a valid cap
- style or an abbreviation of one of these names, then an
- error message is stored in _i_n_t_e_r_p->_r_e_s_u_l_t, TCL_ERROR is
- returned, and *_c_a_p_P_t_r 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 _c_a_p. If _c_a_p isn't a legal
- cap style, then ``unknown cap style'' is returned.
