Chapter 28 Pragmas for Standard C Conformance

Syntax

#pragma ignore_oldstyle on | off | reset

Remarks

If you enable this pragma, the compiler ignores old-style function declarations and lets you prototype a function any way you want. In old-style declarations, you specify the types of arguments on separate lines instead of the function's argument list. For example,

the code in Listing 28-1 on page 429 defines a prototype for a function with an old-style

definition.

Listing 28-1. Mixing Old-style and Prototype Function Declarations

int f(char x, short y, float z);

#pragma ignore_oldstyle on f(x, y, z) char x; short y; float z;

{

return (int)x+y+z;

}

#pragma ignore_oldstyle reset

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

28.5 only_std_keywords

Controls the use of ISO/IEC keywords.

Syntax

#pragma only_std_keywords on | off | reset

Remarks

The compiler recognizes additional reserved keywords. If you are writing source code that must follow the ISO/IEC C standards strictly, enable the pragma only_std_keywords

.

By default, this pragma is disabled.
