      4 
      5 ASN1_item_new_ex, ASN1_item_new
      6 - create new ASN.1 values
      7 
      8 =head1 SYNOPSIS
      9 
     10  #include <openssl/asn1.h>
     11 
     12  ASN1_VALUE *ASN1_item_new_ex(const ASN1_ITEM *it, OSSL_LIB_CTX *libctx,
     13                               const char *propq);
     14  ASN1_VALUE *ASN1_item_new(const ASN1_ITEM *it);
     15 
     16 =head1 DESCRIPTION
     17 
     18 ASN1_item_new_ex() creates a new B<ASN1_VALUE> structure based on the
     19 B<ASN1_ITEM> template given in the I<it> parameter. If any algorithm fetches are
     20 required during the process then they will use the B<OSSL_LIB_CTX> provided in
     21 the I<libctx> parameter and the property query string in I<propq>. See
     22 L<crypto(7)/ALGORITHM FETCHING> for more information about algorithm fetching.
     23 
     24 ASN1_item_new() is the same as ASN1_item_new_ex() except that the default
     25 B<OSSL_LIB_CTX> is used (i.e. NULL) and with a NULL property query string.
     26 
     27 =head1 RETURN VALUES
     28 
     29 ASN1_item_new_ex() and ASN1_item_new() return a pointer to the newly created
     30 B<ASN1_VALUE> or NULL on error.

     32 =head1 HISTORY
     33 
     34 The function ASN1_item_new_ex() was added in OpenSSL 3.0.
