NAME
     alloca - memory allocator



SYNOPSIS
     #include <stdlib.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 on return.

     space.

SEE ALSO
     pagesize(1),  brk(2),  calloc(3),  malloc(3),  realloc(3)
