Syntax

#error [pp-tokens]

The #error directive causes a diagnostic message, along with any included token arguments, to be produced by the compiler.

Examples

#ifndef (HP_C)
#error "HP_C not defined!"     /* This directive will produce
#endif                            the diagnostic message "HP_C
                                  not defined!"               */

#if TABLE_SIZE % 256 != 0
#error "TABLE_SIZE must be a multiple of 256!"
#endif                         /* This directive will produce
                                  the diagnostic message
                                  "TABLE_SIZE must be a
                                  multiple of 256!           */
