### 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.

||
