NAME
form_driver - command processor for the forms subsystem SYNOPSIS
cc [ flag... ] file... -lform -lcurses [ library... ] #include <form.h> int form_driver(FORM *form, int c); DESCRIPTION
The form_driver() function is the workhorse of the forms subsystem; it checks to determine whether the character c is a forms request or data. If it is a request, the form driver executes the request and reports the result. If it is data (a printable ASCII character), it enters the data into the current position in the current field. If it is not recognized, the form driver assumes it is an application- defined command and returns E_UNKNOWN_COMMAND. Application defined commands should be defined relative to MAX_COMMAND, the maximum value of a request listed below. Form driver requests: REQ_NEXT_PAGE Move to the next page.
