Definition of "used" for Rule 21.3

[rgamble]

The rule states, in part, "The identifiers calloc, malloc, realloc and free shall not be used" but does not define what constitutes a use. Is the following example (intended to be) a violation of Rule 21.3?

Code:

void *(*mymalloc)(size_t) = malloc;

[Steve Montgomery]

I think that "used" here is intended to be "shall not appear in an expression" which would mean that your example violates Rule 21.3.

[misra-c]

With reference to the Glossary definition of used, such an attempt to obfuscate the calling of a prohibited function is still a usage.

Therefore, in the example cited, the function malloc() is being used.
