  The \fBcrypt_genhash_impl()\fR function is called by \fBcrypt\fR(3C) to
  generate the encrypted password \fIplaintext\fR.

  .LP
  The \fIparams\fR argument is an \fIargv\fR-like null-terminated vector of type
  \fBchar *\fR. The first element of \fIparams\fR represents the mechanism token
  name from \fBcrypt.conf\fR(4). The remaining elements of \fIparams\fR represent
  strings of the form <\fBparameter\fR>[=<\fBvalue\fR>] to allow passing in
! additional information from the \fBcrypt.conf\fR entry, such as specifing
  rounds information "\fBrounds=4096\fR".

  .LP
  The \fBcrypt_genhash_impl()\fR function must not \fBfree\fR(3C) \fIctbufflen\fR
  on error.
  .SH RETURN VALUES
- .sp
  .LP
  Upon successful completion, \fBcrypt_genhash_impl()\fR returns a pointer to the
  encoded version of \fIplaintext\fR. Otherwise a null pointer is returned and
  \fBerrno\fR is set to indicate the error.
  .SH ERRORS

  The \fBcrypt_genhash_impl()\fR function will fail if:
