|
|
* 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, b, B, 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 NUL. 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 NUL-terminated.
|
|
*/
|
|
|
|
/*
|
|
* When va_list is not supported we only define vim_snprintf().
|
|
*

* vim_vsnprintf() can be invoked with either "va_list" or a list of
|
|
* "typval_T". When the latter is not used it must be NULL.
