Detailed Description

Unix snprintf implementation.

Version 1.4

  1.4:
    *       integrate in FreeRADIUS's libradius:
    *       Fetched from: http://savannah.gnu.org/cgi-bin/viewcvs/mailutils/mailutils/lib/snprintf.c?rev=1.4
    *       Fetched from: http://savannah.gnu.org/cgi-bin/viewcvs/mailutils/mailutils/lib/snprintf.h?rev=1.4
    *       Replace config.h with autoconf.h
    *       Protect with HAVE_SNPRINTF and HAVE_VSNPRINTF
  1.3:
    *       add #include <config.h> ifdef HAVE_CONFIG_H
    *       cosmetic change, when exponent is 0 print xxxE+00
  instead of xxxE-00
  1.2:
    *       put the program under LGPL.

  1.1:
    *       added changes from Miles Bader
    *       corrected a bug with %f
    *       added support for %#g
    *       added more comments :-)
  1.0:
    *       supporting must ANSI syntaxic_sugars
  0.0:
    *       support %s %c %d
