3931 /*
|
|
|
3932 * This code was included to provide a portable vsnprintf() and snprintf().
|
|
715
|
3933 * Some systems may provide their own, but we always use this one for
|
|
272
|
3934 * consistency.
|
|
|
3935 *
|
|
|
3936 * This code is based on snprintf.c - a portable implementation of snprintf
|
|
|
3937 * by Mark Martinec <mark.martinec@ijs.si>, Version 2.2, 2000-10-06.
|
|
1189
|
3938 * Included with permission. It was heavily modified to fit in Vim.
|
|
272
|
3939 * The original code, including useful comments, can be found here:
|
|
|
3940 * http://www.ijs.si/software/snprintf/
|
|
|
3941 *
|
|
|
3942 * This snprintf() only supports the following conversion specifiers:
|
|
|
3943 * s, c, d, u, o, x, X, p (and synonyms: i, D, U, O - see below)
|
|
|
3944 * with flags: '-', '+', ' ', '0' and '#'.
|
|
|
3945 * An asterisk is supported for field width as well as precision.
|
|
|
3946 *
|
|
1619
|
3947 * Limited support for floating point was added: 'f', 'e', 'E', 'g', 'G'.
|
|
|
3948 *
|
|
272
|
3949 * Length modifiers 'h' (short int) and 'l' (long int) are supported.
|
|
|
3950 * 'll' (long long int) is not supported.
|
|
|
3951 *
|
|
437
|
3952 * The locale is not used, the string is used as a byte string. This is only
|
|
|
3953 * relevant for double-byte encodings where the second byte may be '%'.
|
|
|
3954 *
|
|
715
|
3955 * It is permitted for "str_m" to be zero, and it is permitted to specify NULL
|
|
|
3956 * pointer for resulting string argument if "str_m" is zero (as per ISO C99).
|
|
272
|
3957 *
|
|
|
3958 * The return value is the number of characters which would be generated
|
|
|
3959 * for the given input, excluding the trailing null. If this value
|
|
715
|
3960 * is greater or equal to "str_m", not all characters from the result
|
|
|
3961 * have been stored in str, output bytes beyond the ("str_m"-1) -th character
|
|
|
3962 * are discarded. If "str_m" is greater than zero it is guaranteed
|
|
272
|
3963 * the resulting string will be null-terminated.
