/**
|
||||
* G_GNUC_MALLOC:
|
||||
*
|
||||
* Expands to the GNU C malloc function attribute if the compiler is gcc.
|
||||
* Declaring a function as malloc enables better optimization of the function.
|
||||
* A function can have the malloc attribute if it returns a pointer which is
|
||||
* guaranteed to not alias with any other pointer when the function returns
|
||||
* (in practice, this means newly allocated memory).
|
||||
* Expands to the
|
||||
* [GNU C `malloc` function attribute](https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#index-functions-that-behave-like-malloc)
|
||||
* if the compiler is gcc.
|
||||
* Declaring a function as `malloc` enables better optimization of the function,
|
||||
* but must only be done if the allocation behaviour of the function is fully
|
||||
* understood, otherwise miscompilation can result.
|
||||
*
|
||||
* A function can have the `malloc` attribute if it returns a pointer which is
|
||||
* guaranteed to not alias with any other pointer valid when the function
|
||||
* returns, and moreover no pointers to valid objects occur in any storage
|
||||
* addressed by the returned pointer.
|
||||
*
|
||||
* In practice, this means that `G_GNUC_MALLOC` can be used with any function
|
||||
* which returns unallocated or zeroed-out memory, but not with functions which
|
||||
* return initialised structures containing other pointers, or with functions
|
||||
* that reallocate memory. This definition changed in GLib 2.58 to match the
|
||||
* stricter definition introduced around GCC 5.
|
||||
*
|
||||
* Place the attribute after the declaration, just before the semicolon.
|
||||
*
|
||||
* See the GNU C documentation for more details.
|
||||
* See the
|
||||
* [GNU C documentation](https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#index-functions-that-behave-like-malloc)

||||
* for more details.
|
||||

|
||||
