5 X509_new, X509_free - X509 certificate ASN1 allocation functions
9 #include <openssl/x509.h>
12 void X509_free(X509 *a);
16 The X509 ASN1 allocation routines, allocate and free an
17 X509 structure, which represents an X509 certificate.
19 X509_new() allocates and initializes a X509 structure.
21 X509_free() frees up the B<X509> structure B<a>.
22 If B<a> is NULL nothing is done.
26 If the allocation fails, X509_new() returns B<NULL> and sets an error
27 code that can be obtained by L<ERR_get_error(3)>.
28 Otherwise it returns a pointer to the newly allocated structure.
30 X509_free() returns no value.
