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.

PARSE.PILNFD : Parameter Identifier List Needs Function Definition

Summary

A nondefining function declaration does not specify a type for one or more of the function parameters.

This class is a strict subset of Incomplete Function Prototype.

For a defining function declaration that does not specify types for all parameters, see Undeclared Parameter.

This warning class is derived from a C/C++ parser warning.

Enabling

Checks for this warning class are enabled by default. However, warning instances of this class that are issued as parser errors (rather than parser warnings) will be discarded when using factory configuration settings. To prevent these instances from being discarded, add the following WARNING_FILTER rule to the project configuration file.

WARNING_FILTER += allow class="Parameter Identifier List Needs Function Definition"

To disable checks for this warning class, add the following WARNING_FILTER rule to the project configuration file.

WARNING_FILTER += discard class="Parameter Identifier List Needs Function Definition"

Example

void f(x);            /* 'Parameter Identifier List Needs Function Definition' warning issued here
                       * ('Incomplete Function Prototype' warning also issued)
                       */

void h(int x);                            /* Types specified for all parameters. */

void i(x){}                               /* Defining function declaration.
                                           * ('Undeclared Parameter' and 'Incomplete Function Prototype' warnings issued here)
                                           */
