    NAME

    form_field_buffer, set_field_buffer, field_buffer, set_field_status, field_status, set_max_field - set and get forms field attributes
     
    

    SYNOPSIS

    cc [ flag... ] file... -lform  -lcurses  [ library... ]
    #include <form.h>
    
    
    
    int set_field_buffer(FIELD *field, int buf, char *value);
    

    char *field_buffer(FIELD *field, int buf);
    

    int set_field_status(FIELD *field, int status);
    

    int field_status(FIELD *field);
    

    int set_max_field(FIELD *field, int max);
    

     

    DESCRIPTION

    set_field_buffer() sets buffer buf of field to value. Buffer 0 stores the displayed contents of the field. Buffers other than 0 are application specific and not used by the forms library routines. field_buffer() returns the value of field buffer buf.

    Every field has an associated status flag that is set whenever the contents of field buffer 0 changes. set_field_status() sets the status flag of field to status. field_status() returns the status of field.

    set_max_field() sets a maximum growth on a dynamic field, or if max=0 turns off any maximum growth.  

    RETURN VALUES

    field_buffer() returns NULL on error.

    field_status() returns TRUE or FALSE.

    set_field_buffer(), set_field_status(), and set_max_field() return one of the following:
