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.
Otherwise it returns a pointer to the newly allocated structure.
X509_free() returns no value.
X509_new() and X509_free() are available in all versions of SSLeay and OpenSSL.
