NAME

       stralloc_ready - provide space in a stralloc

SYNTAX

       #include <libowfat/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.
