alloca - memory allocator
!!SYNOPSIS


__#include __


__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 on return.
!!RETURN VALUE


The __alloca__ function returns a pointer to the
beginning of the allocated space. If the allocation failed,
a __NULL__ pointer is returned.
!!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.
!!BUGS


The __alloca__ function is machine
dependent.
