60 * user reacted to a prompt.
|

61 * Reset: After hitting a key for the hit-return prompt,

|
|

66 * text can be overwritten.
|
|
|
67 * Set: When any message is written to the screen.
|
|
|
68 * msg_nowait No extra delay for the last drawn message.
|

69 * Used in normal_cmd() before the mode message is drawn.

70 * emsg_on_display There was an error message recently. Indicates that there

72 * msg_scroll The next message should not overwrite the current one.

73 * msg_scrolled How many lines the screen has been scrolled (because of

74 * messages). Used in update_screen() to scroll the screen
|
|
|
75 * back. Incremented each time the screen scrolls a line.

3342 * http://www.ijs.si/software/snprintf/

3345 * s, c, d, u, o, x, X, p (and synonyms: i, D, U, O - see below)
|
|
|
3346 * with flags: '-', '+', ' ', '0' and '#'.
|
|
|
3347 * An asterisk is supported for field width as well as precision.
|
|
|
3348 *
|
|
|
3349 * Length modifiers 'h' (short int) and 'l' (long int) are supported.
|

3350 * 'll' (long long int) is not supported.

|

3357 * is greater or equal to str_m, not all characters from the result
