        #define _XOPEN_SOURCE       /* See feature_test_macros(7) */
        #include <unistd.h>

        char *crypt(const char *key, const char *salt);

        #define _GNU_SOURCE         /* See feature_test_macros(7) */
        #include <crypt.h>

        char *crypt_r(const char *key, const char *salt,
                      struct crypt_data *data);

        Link with -lcrypt.

...
        crypt_r() is a reentrant version of crypt().  The structure 
pointed  to
        by  data  is  used  to  store  result data and bookkeeping 
information.
        Other than allocating it, the only thing that the caller should 
do with
        this  structure  is  to  set data->initialized to zero before 
the first
        call to crypt_r().
