Checks whether member access or array casting is allowed in @safe code.

Specification Function Safety


Source safe.d

bool checkUnsafeAccess(Scope* sc, Expression e, bool readonly, bool printmsg);
Check for unsafe access in @safe code:
  1. read overlapped pointers
  2. write misaligned pointers
  3. write overlapped storage classes
Print error if unsafe.
Scope* sc scope
Expression e expression to check
bool readonly if access is read-only
bool printmsg print error message if true
true if error
bool isSafeCast(Expression e, Type tfrom, Type tto);
Determine if it is @safe to cast e from tfrom to tto.
Expression e expression to be cast
Type tfrom type of e
Type tto type to cast e to
true if @safe
bool checkUnsafeDotExp(Scope* sc, Expression e, Identifier id, int flag);
Check for unsafe use of .ptr or .funcptr
Scope* sc context
Expression e expression for error messages
Identifier id ptr or funcptr
int flag DotExpFlag
true if error
