MISRA.STDLIB.CSTRING.MACRO

Macro from 'cstring' library is used.

MISRA-C++ Rule 18-0-5 (required): The unbounded functions of library '<cstring>' shall not be used.

This rule is also covered by MISRA.STDLIB.CSTRING.

[Undefined 5.7]

Rationale

The strcpy, strcmp, strcat, strchr, strspn, strcspn, strpbrk, strrchr, strstr, strtok and strlen functions within the '<cstring>' library can read or write beyond the end of a buffer, resulting in undefined behaviour.

Ideally, a safe string handling library should be used.

Example

#include <cstring>

void fn ( const char_t * pChar )
{
   char_t array [ 10 ];

   strcpy ( array, pChar ); // Non-compliant
}
