DCL05-A. Use typedefs to improve code readability

Use typedef names to improve code readability.

Non-Compliant Code Example

The following declarations of the signal function s

void (*signal(int, void (*)(int)))(int);

Compliant Solution

This compliant solution makes use of the typedef name to specify exactly the same type as in the non-compliant coding example.

typedef void fv(int), (*pfv)(int);
fv *signal(int, fv *);
pfv signal(int, pfv);

Risk Assessment

Code readability is important for discovering and eliminating vulnerabilities.
