X509_new, X509_free - X509 certificate ASN1 allocation functions


 #include <openssl/x509.h>

 X509 *X509_new(void);
 void X509_free(X509 *a);


The X509 ASN1 allocation routines, allocate and free an X509 structure, which represents an X509 certificate.

X509_new() allocates and initializes a X509 structure.

X509_free() frees up the X509 structure a.


If the allocation fails, X509_new() returns NULL and sets an error code that can be obtained by ERR_get_error(3). Otherwise it returns a pointer to the newly allocated structure.

X509_free() returns no value.


ERR_get_error(3), d2i_X509(3)


X509_new() and X509_free() are available in all versions of SSLeay and OpenSSL.
