[PATCH] inttostr: add a new function, inttostr |
Date: |

Hi Paul,
To my surprise, I found that the inttostr module could not convert an
"int" value (tightly) to a string, while it can handle the likes of
uintmax_t, intmax_t, off_t, and even "unsigned int". It does not provide
an "inttostr" function. Of course, I could simply use intmax_t instead,
but I could also use sprintf ;-) The whole point of this module is to
perform the conversion using minimal resources.
However, since inttostr.c is already in use, I couldn't just fill in
the definitions and #include as is done in the other *tostr.c files.
Instead, I've renamed the inttostr.c template to "anytostr.c", and
then added the new, trivial inttostr.c.
Ok to commit?

Subject: [PATCH] inttostr: add a new function, inttostr
The namesake function was not available. The existence of the
template file, inttostr.c makes its addition nontrivial.
* lib/anytostr.c: Rename from inttostr.c.
* lib/inttostr.c: New file.
* modules/inttostr (Files): Add anytostr.c.
* lib/imaxtostr.c: Update use.
* lib/offtostr.c: Likewise.
* lib/uinttostr.c: Likewise.
* lib/umaxtostr.c: Likewise.
