44 .Nd returns the canonicalized absolute pathname
51 .Fn realpath "const char *pathname" "char resolved_path[MAXPATHLEN]"
55 function resolves all symbolic links, extra
57 characters and references to
63 and copies the resulting absolute pathname into
64 the memory referenced by
70 refer to a buffer capable of storing at least
76 function will resolve both absolute and relative paths
77 and return the absolute pathname corresponding to
79 All but the last component of
96 contains the pathname which caused the problem.
100 may fail and set the external variable
102 for any of the errors specified for the library functions
112 This implementation of
114 differs slightly from the Solaris implementation.
117 version always returns absolute pathnames,
118 whereas the Solaris implementation will,
119 under certain circumstances, return a relative
