alloca()?

• unwind 7y ago
  No. Quoting the manual page: The alloca() function allocates 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. That would not work, since the code calling alloca() is the library, and you want the to allocate on the stack frame of the function calling the library. I don't think that is possible, unless you make the library function into a macro (perhaps using ?: on the allocation size).
