68 * Set: When any message is written to the screen.

|
3329 * http://www.ijs.si/software/snprintf/
|

|
|

|
|
|
3332 * s, c, d, u, o, x, X, p (and synonyms: i, D, U, O - see below)
|
|
|
3333 * with flags: '-', '+', ' ', '0' and '#'.
|
|
|
3334 * An asterisk is supported for field width as well as precision.
|
|
|
3335 *
|
|
|
3336 * Length modifiers 'h' (short int) and 'l' (long int) are supported.
|
|
|
3337 * 'll' (long long int) is not supported.
|

3339 * It is permitted for str_m to be zero, and it is permitted to specify NULL

3340 * pointer for resulting string argument if str_m is zero (as per ISO C99).
|

3341 *
|
|

|
|
|
3343 * for the given input, excluding the trailing null. If this value
|
|
|
3344 * is greater or equal to str_m, not all characters from the result
|
|
|
3345 * have been stored in str, output bytes beyond the (str_m-1) -th character
|

3346 * are discarded. If str_m is greater than zero it is guaranteed
