/*-----------------------------------------------------------------------
Function: gettxstring - Read a string from the keyboard
Arguments: win - Window to use
bufptr - Address of pointer to buffer
multifield - Allow <TAB>, etc, to move between fields
y, x - Start of field (line, col)
fieldsize - Size of field in characters
attr - Curses attribute to use for the field
modified - Pointer to modified status
Returns: int - Status code: OK, ERR or key code
This function calls gettxline() to allow the user to input a string.
Empty strings are specified as the default and the empty values, all
characters are allowed, leading and trailing spaces are automatically
stripped. On entry, the pointer to buffer must either be NULL or
previously allocated with a call to gettxstring(). If *bufptr is NULL,
a buffer of BUFSIZE is automatically allocated using malloc(); this
buffer is used to store the input line. The same exit codes are
returned as returned by gettxline().
