| 30 Description: | |
| 31 The insstr() functions insert a character string into a window | |
| 32 at the current cursor position, by repeatedly calling winsch(). | |
| 33 When PDCurses is built with wide-character support enabled, the | |
| 34 narrow-character functions treat the string as a multibyte | |
| 35 string in the current locale, and convert it first. All | |
| 36 characters to the right of the cursor are moved to the right, | |
| 37 with the possibility of the rightmost characters on the line | |
| 38 being lost. The cursor position does not change (after moving | |
| 39 to y, x, if specified). The routines with n as the last | |
| 40 argument insert at most n characters; if n is negative, then the | |
| 41 entire string is inserted. | |
| 42 | |
| 43 Return Value: | |
| 44 All functions return OK on success and ERR on error. | |
