@deftypefun int strverscmp (const char *@var{s1}, const char *@var{s2})
|
||||
The @code{strverscmp} function compares the string @var{s1} against
|
||||
@var{s2}, considering them as holding indices/version numbers. Return
|
||||
value follows the same conventions as found in the @code{strverscmp}
|
||||
function. In fact, if @var{s1} and @var{s2} contain no digits,
|
||||
@code{strverscmp} behaves like @code{strcmp}.
|
||||
|
||||
Basically, we compare strings normally (character by character), until
|
||||
we find a digit in each string - then we enter a special comparison
|
||||
mode, where each sequence of digits is taken as a whole. If we reach the
|
||||
end of these two parts without noticing a difference, we return to the
|
||||
standard comparison mode. There are two types of numeric parts:
|
||||
"integral" and "fractional" (those begin with a '0'). The types
|
||||
of the numeric parts affect the way we sort them:
|
||||
|
||||
@itemize @bullet
|
||||
@item
|
||||
integral/integral: we compare values as you would expect.
|
||||
|
||||
@item
|
||||
fractional/integral: the fractional part is less than the integral one.
|
||||
Again, no surprise.
|
||||
|
||||
@item
|
||||
fractional/fractional: the things become a bit more complex.
|
||||
If the common prefix contains only leading zeroes, the longest part is less
|
||||
than the other one; else the comparison behaves normally.
|
||||
@end itemize
|
||||
|
||||
@smallexample
|
||||
strverscmp ("no digit", "no digit")
|
||||
@result{} 0 // @r{same behavior as strcmp.}
|
||||
strverscmp ("item#99", "item#100")
|
||||
@result{} <0 // @r{same prefix, but 99 < 100.}
|
||||
strverscmp ("alpha1", "alpha001")
|
||||
@result{} >0 // @r{fractional part inferior to integral one.}
|
||||
strverscmp ("part1_f012", "part1_f01")
|
||||
@result{} >0 // @r{two fractional parts.}
|
||||
strverscmp ("foo.009", "foo.0")
|
||||
@result{} <0 // @r{idem, but with leading zeroes only.}
|
||||
@end smallexample
|
||||
|
||||
This function is especially useful when dealing with filename sorting,
|
||||
because filenames frequently hold indices/version numbers.
