NAMEinsstr, insnstr, winsstr, winsnstr, mvinsstr, mvinsnstr, mvwinsstr, mvwinsnstr - insert string before cursor in a curses window
DESCRIPTIONThese routines insert a character string (as many characters as will fit on the line) before the character under the cursor. All characters to the right of the cursor are shifted 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 functions with n as the last argument insert a leading substring of at most n characters. If n<=0, then the entire string is inserted.
Special characters are handled as in addch.
RETURN VALUEAll routines that return an integer return ERR upon failure and OK (SVr4 specifies only "an integer value other than ERR") upon successful completion, unless otherwise noted in the preceding routine descriptions.
X/Open defines no error conditions. In this implementation, if the window parameter is null or the str parameter is null, an error is returned.
NOTESNote that all but winsnstr may be macros.
PORTABILITYThese functions are described in the XSI Curses standard, Issue 4, which adds const qualifiers to the arguments.
The Single Unix Specification, Version 2 states that insnstr and winsnstr perform wrapping. This is probably an error, since it makes this group of functions inconsistent. Also, no implementation of curses documents this inconsistency.
