By using special #defined values for the column value in the call to v_stpl() and v_stattpl(), you can center, right-justify, or left-justify your string output. The #defined values available are:
| CENTER_TEXT | Centers the specified string in the window buffer. |
| RIGHT_TEXT | Right justifies the string in the window buffer. |
| LEFT_TEXT | Left justifies the string in the window buffer. |
For example, to center the string "Hello, world!" in the fourth row (row number 3) of the buffer associated with the window ex_wnp, call:
|
When right-justification is specified, the last character of the string is placed in the right-most position of the specified window buffer row. When left-justification is specified, the first character of the string is placed in the left-most position of the specified window buffer row. If the string is too long and cannot be centered or right-justified, the function will start output in the first column of the specified row of the buffer.
