NAME
       stralloc_ready - provide space in a stralloc

SYNTAX
       #include <stralloc.h>

       int stralloc_ready(stralloc* sa,size_t len);

DESCRIPTION
       stralloc_ready  makes  sure  that sa has enough space allocated to hold
       len bytes: If sa is not allocated, stralloc_ready  allocates  at	 least
       len  bytes of space, and returns 1. If sa is already allocated, but not
       enough to hold len bytes, stralloc_ready allocates at least  len	 bytes
       of  space,  copies  the	old  string  into the new space, frees the old
       space, and returns 1. Note that this changes sa.s.

       If stralloc_ready runs out of memory, it leaves sa alone and returns 0.

RETURN VALUE
       1 for success, 0 on memory allocation failure.
