147 threads simultaneously, and the string it returns will be overwritten
166 Instead of static storage, it uses the memory pointed to by its

169 @var{data} objects are used in each thread.  The string it returns

176 After that, it can be reused for many calls to @code{crypt_r} without
177 erasing it again.  @code{struct crypt_data} is very large, so it is
178 best to allocate it with @code{malloc} rather than as a local
