/*

weditstr() - edit string
|
|
|
|
Description:
|
|
The initial value of 'str' with a maximum length of 'field' - 1,
|
|
which is supplied by the calling routine, is editted. The user's
|
|
erase (^H), kill (^U) and delete word (^W) chars are interpreted.
|
|
The PC insert or Tab keys toggle between insert and edit mode.
|
|
Escape aborts the edit session, leaving 'str' unchanged.
|
|
Enter, Up or Down Arrow are used to accept the changes to 'str'.
|
|
NOTE: editstr(), mveditstr(), and mvweditstr() are macros.
|
|
|
|
Return Value:
|
|
Returns the input terminating character on success (Escape,
|
|
Enter, Up or Down Arrow) and ERR on error.
|
|
|
|
Errors:
|
|
It is an error to call this function with a NULL window pointer.
|
|
The length of the initial 'str' must not exceed 'field' - 1.
