Hi folks, over at <http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html> one can read the following: ---- malloc The malloc attribute is used to tell the compiler that a function may be treated as if any non-NULL pointer it returns cannot alias any other pointer valid when the function returns and that the memory has undefined content. This will often improve optimization. Standard functions with this property include malloc and calloc. realloc-like functions do not have this property as the memory pointed to does not have undefined content. --- I'm confused about the mentioning of calloc() in this place. Isn't it one of the semantic differences between malloc() and calloc() that the buffer whose address is returned by calloc() is zero-initialized? Thanks in advance for any insights, // Oliver
