The additions include: support the "e", "E", "g", "G", and + * "F" conversion specifiers (and use conversion style "f" or "F" for the + * still unsupported "a" and "A" specifiers); support the "hh", "ll", "j", + * "t", and "z" length modifiers; support the "#" flag and the (non-C99) + * "'" flag; use localeconv(3) (if available) to get both the current + * locale's decimal point character and the separator between groups of + * digits; fix the handling of various corner cases of field width and + * precision specifications; fix various floating point conversion bugs; + * handle infinite and NaN floating point values; don't attempt to write to + * the output buffer (which may be NULL) if a size of zero was specified; + * check for integer overflow of the field width, precision, and return + * values and during the floating point conversion; use the OUTCHAR() macro + * instead of a function for better performance; provide asprintf(3) and + * vasprintf(3) functions; add new test cases. The replacement functions + * have been renamed to use an "rpl_" prefix, the function calls in the + * main project (and in this file) must be redefined accordingly for each + * replacement function which is needed (by using Autoconf or other means). + * Various other minor improvements have been applied and the coding style + * was cleaned up for consistency. + * + * 2007-07-23 Holger Weiss <holger@jhweiss.de> for Mutt 1.5.13: + * + * C99 compliant snprintf(3) and vsnprintf(3) functions return the number + * of characters that would have been written to a sufficiently sized + * buffer (excluding the '\0').
