- ** wn_gpword(fun,frm,fld,wn,row,col,prmpt,atrib,fill,fwidth,ubuff,hlpmsg,errmsg)
- **
- ** int fun - fucntion code (SET || XEQ)
- ** (WIFORM) frm - form pointer (actual || NFRM)
- ** int fld - field # in form (actual || NFLD)
- ** (WINDOWPTR) wn - window pointer
- ** int row - row in window where data input begins
- ** int col - col in window where data input begins
- ** (char *) prmpt - field promt (call with NSTR for none)
- ** unsigned atrib - field (not prompt) atributes
- ** char fill - field fill character
- ** int fwidth - width of mask (maximum # of digits is MAXSTR)
- ** (char *) ubuff - pointer to char array of fwidth+2 bytes for editing
- ** (char *)hlpmsg - pointer to help message (call with NSTR for none)
- ** (char *)errmsg - pointer to err message (call with NSTR) for none)
- **
- ** RETURNS:
- **
- ** UBUFF with text data via pointer.
- **
- ** NULL if error, else the non zero value returned from wn_input.
- **
- ** NOTES:
- **
- ** FUN - fun can only be SET for form setup, or XEQ for immediate
- ** execution. When called with SET, valid arguements for both
- ** "frm" and "fld" must be specfied. frm is the field pointer
- ** returned from frmopn(), and fld is the field sequence number
- ** in the form for this field. When called with XEQ frm must
- ** be NFRM and fld must NFLD.
- **
- ** UBUFF - Editing buffer. Must be of sufficent size to hold the
- ** data as it is entered. Typical value is the length
- ** of the mask + 2 bytes (strlen(mask)+2).
- **
- ** On entry, the first byte of ubuff should be
- ** a null, otherwise wn_input assumes there is valid
- ** data there and will enter edit mode. This can be
- ** handy if there is a need for prefilled but editable
- ** fields. In actual pratice, wn_input uses this
- ** buffer for both initial character data entry and
- ** subsequent editing.
- **
- ** On return, ubuff contains the actual data entered in
- ** character format with fill and mask characters as
- ** spaces (e.g. "This is a line of text ").
- **
- ** Calls wn_input to perform data entry.
- **
- ** No validation is performed.
