asn1_bit_der(3)			   libtasn1		       asn1_bit_der(3)

NAME
       asn1_bit_der - API function

SYNOPSIS
       #include	<libtasn1.h>

       void asn1_bit_der(const unsigned	char * str, int	bit_len, unsigned char
       * der, int * der_len);

ARGUMENTS
       const unsigned char * str
		   BIT string.

       int bit_len number of meaningful	bits in	STR.

       unsigned	char * der
		   string returned.

       int * der_len
		   number of meaningful	bytes of DER (der[0]..der[ans_len-1]).

DESCRIPTION
       Creates a length-value DER encoding for the input data as it would have
       been for	a BIT STRING.  The DER encoded data will be copied in  der .

       Note that the BIT STRING	tag is not included in the output.

       This  function  does  not  return any value because it is expected that
       der_len will contain enough bytes to store the string plus the DER  en-
       coding. The DER encoding	size can be obtained using asn1_length_der().
