Skip leading and trailing whitespace characters in the string indicated by the specified `&ast;begin` and `&ast;end` iterators by appropriately advancing `&ast;begin` and regressing `&ast;end`&period; If the indicated string is empty, or consists solely of whitespace characters, `&ast;begin` is unchanged and `&ast;end` is regressed to `&ast;begin`&period; Otherwise, advance `&ast;begin` to the first non&hyphen;whitespace character whose position is greater than or equal to `&ast;begin` and regress `&ast;end` to one past the position of the last non&hyphen;whitespace character whose position is less than `&ast;end`&period; The indicated string need not be null&hyphen;terminated and may contain embedded null (&apos;0&apos;) characters&period; The behavior is undefined unless `&ast;begin &lt;&equals; &ast;end`&period; Note that since `&ast;begin` and `&ast;end` are iterators, `&ast;end` refers to the character one past the end of the subject string&period;
