3651 * This code was included to provide a portable vsnprintf() and snprintf().
|
|
|
3652 * Some systems may provide their own, but we always use these for
|
|
|
3653 * consistency.
|
|
|
3654 *
|
|
|
3655 * This code is based on snprintf.c - a portable implementation of snprintf
|
|
|
3656 * by Mark Martinec <mark.martinec@ijs.si>, Version 2.2, 2000-10-06.
|
|
291
|
3657 * Included with permission. It was heavely modified to fit in Vim.
|
|
272
|
3658 * The original code, including useful comments, can be found here:
|
|
|
3659 * http://www.ijs.si/software/snprintf/
|
|
|
3660 *
|
|
|
3661 * This snprintf() only supports the following conversion specifiers:
|
|
|
3662 * s, c, d, u, o, x, X, p (and synonyms: i, D, U, O - see below)
|
|
|
3663 * with flags: '-', '+', ' ', '0' and '#'.
|
|
|
3664 * An asterisk is supported for field width as well as precision.
|
|
|
3665 *
|
|
|
3666 * Length modifiers 'h' (short int) and 'l' (long int) are supported.
|
|
|
3667 * 'll' (long long int) is not supported.
|
|
|
3668 *
|
|
437
|
3669 * The locale is not used, the string is used as a byte string. This is only
|
|
|
3670 * relevant for double-byte encodings where the second byte may be '%'.
|
|
|
3671 *
|
|
272
|
3672 * It is permitted for str_m to be zero, and it is permitted to specify NULL
|
|
|
3673 * pointer for resulting string argument if str_m is zero (as per ISO C99).
|
|
|
3674 *
|
|
|
3675 * The return value is the number of characters which would be generated
|
|
|
3676 * for the given input, excluding the trailing null. If this value
|
|
|
3677 * is greater or equal to str_m, not all characters from the result
|
|
|
3678 * have been stored in str, output bytes beyond the (str_m-1) -th character
|
|
|
3679 * are discarded. If str_m is greater than zero it is guaranteed
|
|
|
3680 * the resulting string will be null-terminated.
