| \brief Allocate \a __size bytes of space in the stack frame of the caller. |
| |
| This temporary space is automatically freed when the function that |
| called alloca() returns to its caller. Avr-libc defines the alloca() as |
| a macro, which is translated into the inlined \c __builtin_alloca() |
| function. The fact that the code is inlined, means that it is impossible |
| to take the address of this function, or to change its behaviour by |
| linking with a different library. |
| |
| \return alloca() returns a pointer to the beginning of the allocated |
| space. If the allocation causes stack overflow, program behaviour is |
| undefined. |
| |
| \warning Avoid use alloca() inside the list of arguments of a function |
| call. |
