What is the use of aligned attribute in GCC?
The aligned attribute can also be used for variables and fields (see Variable Attributes .) The alloc_size attribute is used to tell the compiler that the function return value points to memory, where the size is given by one or two of the functions parameters. GCC uses this information to improve the correctness of __builtin_object_size .

What is inline attribute in GCC?
For functions declared inline, this attribute inlines the function even if no optimization level was specified. This attribute should be used with a function which is also declared with the inline keyword. It directs GCC to treat the function as if it were defined in gnu90 mode even when compiling in C99 or gnu99 mode.
