Good point, one should read the full context and not
just grepping around ;-)
8798 Pathname Variable Values
8799 The values in the following list may be constants within an
implementation or may vary from
8800 one pathname to another. For example, file systems or directories
may have different
8801 characteristics.
8802 A definition of one of the values shall be omitted from the
<limits.h> header on specific
8803 implementations where the corresponding value is equal to or
greater than the stated minimum,
8804 but where the value can vary depending on the file to which it is
applied. The actual value
8805 supported for a specific pathname shall be provided by the
pathconf( ) function.
[...]
8825 {PATH_MAX}
8826 Maximum number of bytes in a pathname, including the
terminating null character.
8827 Minimum Acceptable Value: {_POSIX_PATH_MAX}
8828 XSI Minimum Acceptable Value: {_XOPEN_PATH_MAX}
AM: Interpretation is left up to the reader ... :-)
Nevertheless, the point was just whether "something" like
this still exists in Posix. And the answer is, it did
and will exist.
