New Revision: 309035
URL: https://svnweb.freebsd.org/changeset/base/309035
Log:
This little BSD licensed library has been kicking around for years.
It allows one to trivially convert an absolute path to a relative path
and the reverse. The test programs themselves are very useful in scripts
but the real use comes shortly with the -r and -a arguments to ln.
These are sometimes known as the --relative and --absolute flags and
can force a symlink to be relative when you only have an absolue path.
Another place these are sometimes used is to add -a and -r args to 'realpath'.
Incredibly useful in Makefiles.
I was going to just add the files in with 'ln' but a library makes more sense.
The test programs may come out in their own right some day for scripting.

The test directry does not conform to any framework.
Not connected to build.

+.Sh NAME
+.Nm abs2rel
+.Nd make a relative path name from an absolute path name
+.Sh SYNOPSIS
+.Ft "char *"
+.Fn abs2rel "const char *path" "const char *base" "char *result" "size_t size"
+.Sh DESCRIPTION
+The
+.Fn abs2rel
+function makes a relative path name from an absolute path name
+.Fa path
+based on a directory
+.Fa base
+and copies the resulting path name into the memory referenced by
+.Fa result .
+The
+.Fa result
+argument must refer to a buffer capable of storing at least
+.Fa size
+characters.
+
+The resulting path name may include symbolic links.
+The
+.Fn abs2rel
+function doesn't check whether or not any path exists.
+.Sh "RETURN VALUES"
+The
+.Fn abs2rel
+function returns relative path name on success.
+If an error occurs,
+it returns
+.Dv NULL .
+.Sh ERRORS
+The
+.Fn abs2rel
+function may fail and set the external variable
+.Va errno
+to indicate the error.
+.Bl -tag -width Er
+.It Bq Er EINVAL
+The
+.Fa base
+directory isn't an absolute path name or the
+.Fa size
+argument is zero.
+.It Bq Er ERANGE
+The
+.Fa size
+argument is greater than zero but smaller than the length of the pathname plus 1.
+.Sh EXAMPLE
+ char result[MAXPATHLEN];
+ char *path = abs2rel("/usr/src/sys", "/usr/local/lib", result, MAXPATHLEN);
+
+yields:
+
+ path == "../../src/sys"
+
+Similarly,
+
+ path1 = abs2rel("/usr/src/sys", "/usr", result, MAXPATHLEN);
+ path2 = abs2rel("/usr/src/sys", "/usr/src/sys", result, MAXPATHLEN);
+
+yields:
+
+ path1 == "src/sys"
+ path2 == "."
+
+.Sh BUGS
+If the
+.Fa base
+directory includes symbolic links,
+the
+.Fn abs2rel
+function produces the wrong path.
+For example, if '/sys' is a symbolic link to '/usr/src/sys',
+
+ char *path = abs2rel("/usr/local/lib", "/sys", result, MAXPATHLEN);
+
+yields:
+
+ path == "../usr/local/lib" /* It's wrong!! */
+
+You should convert the base directory into a real path in advance.
+.Pp
+
+ path = abs2rel("/sys/kern", realpath("/sys", resolvedname), result, MAXPATHLEN);
+
+yields:
+
+ path == "../../../sys/kern" /* It's correct but ... */
+
+That is correct, but a little redundant. If you wish get the simple
+answer 'kern', do the following.
+
+ path = abs2rel(realpath("/sys/kern", r1), realpath("/sys", r2),
+ result, MAXPATHLEN);
+
+The
+.Fn realpath
+function assures correct result, but don't forget that
+.Fn realpath
+requires that all but the last component of the path exist.
