Pragmas for the DSP56800 and DSP56800E

Pragma Reference

377Targeting MC56F83xx/DSP5685x Controllers

Listing C.2 Unnamed Arguments

void f(int ) {} /* OK, if ANSI Strict is disabled */

void f(int i) {} /* ALWAYS OK */

•A # token that does not appear before an argument in a macro definition. Listing

C.3 shows an example.

Listing C.3 Using # in Macro Definitions

#define add1(x) #x #1

/* OK, if ANSI_strict is disabled,

but probably not what you wanted:

add1(abc) creates "abc"#1 */

#define add2(x) #x "2"

/* ALWAYS OK: add2(abc) creates "abc2" */

• An identifier after #endif. Listing C.4 shows an example.

Listing C.4 Identifiers After #endif

#ifdef __MWERKS__

/* . . . */

#endif __MWERKS__ /* OK, if ANSI_strict is disabled */

#ifdef __MWERKS__

/* . . . */

#endif /*__MWERKS__*/ /* ALWAYS OK */

This pragma corresponds to the ANSI Strict setting in the C/C++ Language panel. To

check this setting, use __option (ANSI_strict), described in Checking

Settings. By default, this pragma is disabled.
