FOPEN (3S) FOPEN (3S) may be used to reposition the file pointer to any position in the file, but when output is written to the file the current file pointer is disregarded. All output is written at the end of the file and causes the file pointer to be repositioned at the end of the output. If two separate processes open the same file for append, each process may write freely to the file without fear of destroying output � being written by the other. The output from the two processes will be intermixed in the file in the order in which it is written. SEE ALSO open(2), fclose(3S). DIAGNOSTICS Fopen and [reopen return a NULL pointer on failure. - 2-
FORM ( 3T ) ( AT&T UNIX PC only ) FORM ( 3T ) NAME form - display and accept forms SYNOPSIS #include #include int fo rm( form, op) form_t *form; int op; DESCRIPTION This routine manipulates a form as determined by the operation code ( op ) . If the op arg is F _BEGIN, the form is initialized and displayed. If op is F _INPUT, user input is accepted. If op is F _END, the form is terminated and removed from the display. These functions may be combined in many ways. By specifying (F _BEGIN IF _INPUT IF _END), the caller creates a "pop-up" form which is initialized (displayed), used for input, then removed. Generally, (F _BEGIN IF _INPUT) is used for the first call, F _INPUT for each subsequent interaction, and F _END when the form is to be discarded. During the F _INPUT function, the user may point to fields with the mouse or with the keyboard (arrows, Prev, Next, Beg, Home, End, Tab). The user may may modify fields by typing and editing (Back Space, Dlete Char, Clear Line, Cancel) or by selecting a choice from a menu optionally associated with the field. The form structure has the following form: typedef struct { char char char int track_t field_t field_t } form_t; *f_label; *f_name; f_fl.ags; f_win; *f_track; *f_fields; *f_curfl; I* form label *I I* form name *I I* form flags *I I* form window *I I* tracking info *I I* fields *I I* current field *I F_label is the form label, displayed on the window label line of the form. If /_label is NULL, no label is displayed. F _name is the form name, or NULL if the form has no name. F _flags contains flags. The F _ WINNEW flag causes form to use the "new " algorithm to place the window. Basically, the new algorithm looks for relatively empty screen space to place the window. F_WINSON causes form to use the "son" algorithm which causes the new window to slightly overlap the current window. If neither F _ WINNEW nor F _WINSON is given, the "popup" algorithm is used. This causes the new window to appear near the middle of the current window, inside it if possible. F _NO MOVE is set if the - 1 -
