Audit readlink(1) 1) Properly document e, f and m-flags in the manpage. 2) Clear up the code for the m-flag-handling. Add idiomatic '/'-path-traversal as already seen in mkdir(1). 3) Unwrap the SWAP_BUF()-macro. 4) BUGFIX: Actually handle the f-flag properly. Only resolve the dirname and append the basename later. 5) Use fputs() instead of printf("%s", ...). 2015-03-20 17:09:47 -04:00			`.Dd March 20, 2015`
