LANG.FUNCS.SAP : Static Array Parameter

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.

A function has an array parameter whose declaration includes the static keyword between the [ ].

This check only applies to C code built in C99 mode: C90 and C++ do not include static array parameters.

Enabling

Checks for this warning class are disabled by default, and require the unnormalized C ASTs for the project. To enable them, add the following WARNING_FILTER rule and RETAIN_UNNORMALIZED_C_AST specification to the project configuration file.

RETAIN_UNNORMALIZED_C_AST = Yes
WARNING_FILTER += allow class="Static Array Parameter"

Note that retaining the unnormalized ASTs will increase the disk space used to store the project representation, and may make the analysis take longer.

void decl_static(char a[static 20]);  /* 'Static Array Parameter' warning issued here */

void decl_nostatic(char a[20]);                            /* no static keyword between [ ] */

void decl_nosize(char a[]);                                /* no static keyword between [ ] */

const int ten=10;

void def(char a[static ten],          /* 'Static Array Parameter' warning issued here */
         char b[ten]){                                     /* no static keyword between [ ] */
