 DESCRIPTION

Tk_GetJustify places in *justifyPtr the justify value
corresponding to string. This value will be one of the following:

TK_JUSTIFY_LEFT
Means that the text on each line should start at the left edge of
the line; as a result, the right edges of lines may be ragged.

TK_JUSTIFY_RIGHT
Means that the text on each line should end at the right edge of
the line; as a result, the left edges of lines may be ragged.

TK_JUSTIFY_CENTER
Means that the text on each line should be centered; as a result,
both the left and right edges of lines may be ragged.

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

Tk_NameOfJustify is the logical inverse of Tk_GetJustify.
Given a justify value it returns a statically-allocated string
corresponding to justify.
If justify isn't a legal justify value, then
``unknown justification style'' is returned.
