d2i_X509_CRL, i2d_X509_CRL, d2i_X509_CRL_bio, d2i_509_CRL_fp,

i2d_X509_CRL_bio, i2d_X509_CRL_fp - PKCS#10 certificate request functions.

=head1 SYNOPSIS

 #include <openssl/x509.h>

 DH *d2i_X509_CRL(X509_CRL **a, unsigned char **pp, long length);

 int i2d_X509_CRL(X509_CRL *a, unsigned char **pp);

 X509_CRL *d2i_X509_CRL_bio(BIO *bp, X509_CRL **x);

 X509_CRL *d2i_X509_CRL_fp(FILE *fp, X509_CRL **x);

 int i2d_X509_CRL_bio(X509_CRL *x, BIO *bp);

 int i2d_X509_CRL_fp(X509_CRL *x, FILE *fp);

=head1 DESCRIPTION

These functions decode and encode an X509 CRL (certificate revocation

list).

Othewise the functions behave in a similar way to d2i_X509() and i2d_X509()

described in the L<d2i_X509(3)|d2i_X509(3)> manual page.
