Error Directive (#error)

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 56!"
#endif /* This directive will produce
the diagnostic message
"TABLE_SIZE must be a
multiple of 256! */

	NOTE: The #error directive is only supported in ANSI mode.
