| 67 * text can be overwritten. | |
| 68 * Set: When any message is written to the screen. | |
| 69 * msg_nowait No extra delay for the last drawn message. | |
| 70 * Used in normal_cmd() before the mode message is drawn. | |
| 71 * emsg_on_display There was an error message recently. Indicates that there | |
| 72 * should be a delay before redrawing. | |
| 73 * msg_scroll The next message should not overwrite the current one. | |
| 74 * msg_scrolled How many lines the screen has been scrolled (because of | |
| 75 * messages). Used in update_screen() to scroll the screen | |
| 76 * back. Incremented each time the screen scrolls a line. | |

| 7 | 83 * need_wait_return TRUE when the hit-return prompt is needed. |

| 85 * has answered some other prompt. | |
| 86 * Set: When the ruler or typeahead display is overwritten, | |
| 87 * scrolling the screen for some message. | |

| 272 | 4148 * This code was included to provide a portable vsnprintf() and snprintf(). |
| 715 | 4149 * Some systems may provide their own, but we always use this one for |
| 272 | 4150 * consistency. |
| 4151 * | |
| 4152 * This code is based on snprintf.c - a portable implementation of snprintf | |
| 4153 * by Mark Martinec <mark.martinec@ijs.si>, Version 2.2, 2000-10-06. | |
| 1189 | 4154 * Included with permission. It was heavily modified to fit in Vim. |
| 272 | 4155 * The original code, including useful comments, can be found here: |
| 4156 * http://www.ijs.si/software/snprintf/ | |
| 4157 * | |
| 4158 * This snprintf() only supports the following conversion specifiers: | |
| 4159 * s, c, d, u, o, x, X, p (and synonyms: i, D, U, O - see below) | |
| 4160 * with flags: '-', '+', ' ', '0' and '#'. | |
| 4161 * An asterisk is supported for field width as well as precision. | |
| 4162 * | |

| 272 | 4173 * |
| 4174 * The return value is the number of characters which would be generated | |

| 715 | 4176 * is greater or equal to "str_m", not all characters from the result |
| 4177 * have been stored in str, output bytes beyond the ("str_m"-1) -th character | |
