*
* 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.
*
