| /* |
| * This code was included to provide a portable vsnprintf() and snprintf(). |
| * Some systems may provide their own, but we always use this one for |
| * consistency. |
| * |
| * This code is based on snprintf.c - a portable implementation of snprintf |
| * by Mark Martinec <mark.martinec@ijs.si>, Version 2.2, 2000-10-06. |
| * Included with permission. It was heavily modified to fit in Vim. |
| * The original code, including useful comments, can be found here: |
| * http://www.ijs.si/software/snprintf/ |
| * |
| * This snprintf() only supports the following conversion specifiers: |
| * s, c, d, u, o, x, X, p (and synonyms: i, D, U, O - see below) |
| * with flags: '-', '+', ' ', '0' and '#'. |
| * An asterisk is supported for field width as well as precision. |
| * |
| * Limited support for floating point was added: 'f', 'e', 'E', 'g', 'G'. |
| * |
| * Length modifiers 'h' (short int) and 'l' (long int) are supported. |
| * 'll' (long long int) is not supported. |
| * |
| * The locale is not used, the string is used as a byte string. This is only |
| * relevant for double-byte encodings where the second byte may be '%'. |
| * |
| * It is permitted for "str_m" to be zero, and it is permitted to specify NULL |
| * pointer for resulting string argument if "str_m" is zero (as per ISO C99). |
| * |
| * The return value is the number of characters which would be generated |
| * for the given input, excluding the trailing null. If this value |
| * is greater or equal to "str_m", not all characters from the result |
| * have been stored in str, output bytes beyond the ("str_m"-1) -th character |
| * are discarded. If "str_m" is greater than zero it is guaranteed |
| * the resulting string will be null-terminated. |
| */ |
| |
| /* |
| * When va_list is not supported we only define vim_snprintf(). |
