According to Bruno Haible on 5/9/2008 5:50 PM:
| Going a bit farther than Eric's xmemdup0 function, I would like to propose
| a module 'xstring' with an <xstring.h> header file that defines the
following
| functions:
|
|   /* Return a substring of the given string, len bytes long starting at
str.  */
|   char * xsubstring (const char *str, size_t len);

How is this different from [x]strndup?  At least strndup is standardized.

|
|   /* Duplicate a string. Moved here from xalloc.h. Keeps being declared in
|      xalloc.h for a transition period, with a warning if it's used from
there
|      (a migration aid).  */
|   char * xstrdup (const char *string);
|
|
| Comments? Additions?

The remaining functions looked reasonable from a first glance.
