alloca
ALLOCA(3) Linux Programmer's Manual ALLOCA(3)
NAME
alloca - memory allocator
SYNOPSIS
#include <alloca.h>
void *alloca(size_t size);
DESCRIPTION
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.
RETURN VALUE
The alloca function returns a pointer to the beginning of the allocated space. If the allocation causes stack overflow, program behaviour
is undefined.
CONFORMING TO
There is evidence that the alloca function appeared in 32v, pwb, pwb.2, 3bsd, and 4bsd. There is a man page for it in BSD 4.3. Linux uses
the GNU version. This function is not in POSIX or SUSv3.
NOTES ON THE GNU VERSION
Normally, gcc translates calls to alloca by inlined code. This is not done when either the -ansi or the -fno-builtin option is given. But
beware! By default the glibc version of <stdlib.h> includes <alloca.h> and that contains the line
# define alloca(size) __builtin_alloca (size)
with messy consequences if one has a private version of this 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.
The inlined code often consists of a single instruction adjusting the stack pointer, and does not check for stack overflow. Thus, there is
no NULL error return.
BUGS
The alloca function is machine and compiler dependent. On many systems its implementation is buggy. Its use is discouraged.
On many systems alloca cannot be used inside the list of arguments of a function call, because the stack space reserved by alloca would
appear on the stack in the middle of the space for the function arguments.
