DESCRIPTION
This implements a curses based message display system. A source file that lists messages with associated names is given to msgc and produces
both a .c and a .h file that implement the menu system. The standard root name of the files is msg_defs. The -o name can be used to specify
a different root name.
ENVIRONMENT
MSGDEF Can be set to point to a different set of definition files for msgc. The current location defaults to /usr/share/misc.
FILES
/usr/share/misc/msg_sys.def
SOURCE DESCRIPTION
The format is very simple. Each message is started with the word 'message' followed by the name of the message. The body of the message is
next and is started by a { and closed by a }. The braces are not part of the message. Everything, including newlines between the braces are
part of the message.
MESSAGE FUNCTIONS
The defined messages are used through calls routines that manipulate the messages. You first need to set the curses(3) environment up and
then tell the message system which window to use for displaying message by calling the function msg_window().
All variable argument lists in the functions are used as are arguments to sprintf(3). The messages may have sprintf(3) conversions in them
and the corresponding parameters should match. Messages are identified by name using the notation 'MSG_name' where ``name'' is the name in
the message source file. (The definitions are accessed by including the generated .h file into a source file wanting to use the message rou-
tines.)
The function msg_string() just returns a pointer to the actual message string. The functions msg_clear(), msg_standout() and msg_standend()
respectively clear the message window, set standout mode and clear standout mode.
The functions msg_display() and msg_display_add() cause a defined message to be displayed in the message window and does the requested con-
versions before printing. The difference is that msg_display() clears the window before displaying the message. These functions fill para-
graphs for readability. The msg_table_add() function behaves like msg_display_add() but does not fill text.
The remaining functions deal with a prompt facility. A prompt message is either taken from the message directory or from a given string.
The message is processed with sprintf(3) and then displayed. If the parameter def is non-NULL and not a string of zero length, a default
value is printed in brackets. The user is allowed to type in a response. If the user types just the newline character, the default is
returned in the value. The parameter max_chars is the length of the parameter val, where the results are stored. The parameters def and val
may point to the same character array. If the default is chosen, the character array is not changed. The functions msg_echo() and
msg_noecho() control whether the prompt routine echo or don't echo the input that is typed by the user.
msg_prompt_win() uses the specified curses window instead of the default one.
msg_row() return the current row - i.e.: getcury(msg_win) + getbegy(msg_win).
