JavaScript is not currently enabled, but is required for full CodeSonar manual search and browse functionality.

If you are viewing this file in your hub's Web GUI, enable JavaScript in your browser: you will also need it for GUI functionality.

If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

CERT-C

CERT-C:PRE00-C

Prefer inline or static functions to function-like macros

CERT-C:PRE31-C

The #define pre-processor directive shall not be used to create inline macros. Inline functions shall be used instead.

Example

#define ONE 1                                       /* not function-like */
#define TWO (2)                                     /* not function-like */
#define THREE()(3)      /* 'Function-Like Macro' warning issued here */
#define FOUR(a)(4)      /* 'Function-Like Macro' warning issued here */
#define ADD(a,b)(a+b)   /* 'Function-Like Macro' warning issued here */

/* Macros do not need to be used in order to trigger 'Function-Like Macro' warnings. */
