39 .Nd returns the canonicalized absolute pathname
46 .Fn realpath "const char *pathname" "char resolved_path[PATH_MAX]"
50 function resolves all symbolic links, extra
52 characters and references to

59 the memory referenced by
65 refer to a buffer capable of storing at least
71 function will resolve both absolute and relative paths
72 and return the absolute pathname corresponding to
74 All but the last component of
91 contains the pathname which caused the problem.
95 may fail and set the external variable
97 for any of the errors specified for the library functions
103 This implementation of
105 differs slightly from the Solaris implementation.
108 version always returns absolute pathnames,
109 whereas the Solaris implementation will,
110 under certain circumstances, return a relative
