|
|
* Description:
|
|
* The insstr() functions insert a character string into a window
|
|
* at the current cursor position, by repeatedly calling winsch().
|
|
* When PDCurses is built with wide-character support enabled, the
|
|
* narrow-character functions treat the string as a multibyte
|
|
* string in the current locale, and convert it first. All
|
|
* characters to the right of the cursor are moved to the right,
|
|
* with the possibility of the rightmost characters on the line
|
|
* being lost. The cursor position does not change (after moving
|
|
* to y, x, if specified). The routines with n as the last
|
|
* argument insert at most n characters; if n is negative, then the
|
|
* entire string is inserted.
|
|
*
|
|
* Return Value:
|
|
* All functions return OK on success and ERR on error.
