NAME
       crypt_gensalt_impl - generate salt for password encryption

SYNOPSIS
       #include <crypt.h>

       char *crypt_gensalt_impl(char *gsbuffer, size_t gsbufflen, const char *oldsalt, const struct passwd *userinfo, const char **params);

DESCRIPTION
       The crypt_gensalt_impl() function is called by crypt_gensalt(3C) to generate the salt for password encryption.

       The gsbuffer argument is a pointer to an MT-safe buffer of size gsbufflen.

       The oldsalt and userinfo arguments are passed unchanged from crypt_gensalt(3C).

       The  params argument is an argv-like null terminated vector of type char *. The first element of params represents the mechanism token name
       from crypt.conf(4). The remaining elements of params represent strings of the form <parameter>[=<value>] to  allow  passing  in	additional
       information from the crypt.conf entry, such as specifying rounds information "rounds=4096".

       The  value returned by crypt_gensalt_impl() points to a thread-specific buffer to be freed by the caller of crypt_gensalt(3C) after calling
       crypt(3C).

RETURN VALUES
       Upon successful completion, crypt_gensalt_impl() returns a pointer to the new salt. Otherwise a null pointer is returned and errno  is  set
       to indicate the error.

ERRORS
       The crypt_gensalt_impl() function will fail if:

       EINVAL	       The configuration file crypt.conf contains an invalid entry.

       ELIBACC	       The required crypt shared library was not found.

       ENOMEM	       There is insufficient memory to perform hashing.
