Chapter 30 Pragmas for Language Translation

Syntax

#pragma mpwc_relax on | off | reset

Remarks

If you enable this pragma, the compiler treats char*

and unsigned char*

as the same type.

Use this setting to compile source code written before the ISO C standards. Old source code frequently uses these types interchangeably.

This setting has no effect on C++ source code.

NOTE

Turning this option on may prevent the compiler from detecting some programming errors. We recommend not turning on this option.

Listing 30-1 on page 463

shows how to use this pragma to relax function pointer checking.

Listing 30-1. Relaxing function pointer checking

#pragma mpwc_relax on extern void f(char *);

/* Normally an error, but allowed. */ extern void(*fp1)(void *) = &f;

/* Normally an error, but allowed. */ extern void(*fp2)(unsigned char *) = &f;

This pragma does not correspond to any panel setting. By default, this pragma is disabled.

30.9 multibyteaware

Controls how the Source encoding option in the IDE is treated

Syntax

#pragma multibyteaware on | off | reset

Remarks

This pragma is deprecated. See

#pragma text_encoding

for more details.

By default, this pragma is off

.
