=head1 SYNOPSIS

 #include <openssl/x509.h>

 X509_REQ *d2i_X509_REQ(X509_REQ **a, unsigned char **pp, long length);
 int i2d_X509_REQ(X509_REQ *a, unsigned char **pp);

 X509_REQ *d2i_X509_REQ_bio(BIO *bp, X509_REQ **x);
 X509_REQ *d2i_X509_REQ_fp(FILE *fp, X509_REQ **x);

 int i2d_X509_REQ_bio(X509_REQ *x, BIO *bp);
 int i2d_X509_REQ_fp(X509_REQ *x, FILE *fp);

=head1 DESCRIPTION

These functions decode and encode a PKCS#10 certificate request.

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