(general)Considers the possibility that fgets() and fgetws() may return empty strings (Warnings of various classes may be triggered depending on subsequent operations on those strings. For example, the noncompliant code example cited above would trigger a buffer underrun warning.)
Compass/ROSE

 

 

Could detect some violations of this rule (In particular, it could detect the noncompliant code example by searching for fgets(), followed by strlen() - 1, which could be −1. The crux of this rule is that a string returned by fgets() could still be empty, because the first char is '\0'. There are probably other code examples that violate this guideline; they would need to be enumerated before ROSE could detect them.)
