LANG.STRUCT.PIT : Pointer Type Inside Typedef

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 pointer type appears inside a typedef statement.

POW10	POW10:9	Limit the use of pointers. Use no more than two levels of dereferencing per expression.
JPL	JPL:28	Do not hide dereference operations inside macros or typedefs.

Availability

Available for C and C++.

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="Pointer Type Inside Typedef"

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

typedef int** mytype_t;    /* 'Pointer Type Inside Typedef' warning issued here */

The following configuration file parameters affect checks for this warning class.
