76 The access time is set to the value of the actime member, and the
77 modification time is set to the value of the modtime member.
78 The times are measured in seconds since 0 hours, 0 minutes, 0

86 Otherwise, a value of \-1 is returned and

108 The pathname contains a character with the high-order bit set.

114 A component of a pathname exceeded 255 characters,
115 or an entire path name exceeded 1023 characters.
117 The named file does not exist.
119 A component of the path prefix is not a directory.

126 does not match the owner of the file and is not the super-user.
128 The file system containing the file is mounted read-only.
