NAMEBIO_new, BIO_up_ref, BIO_free, BIO_vfree, BIO_free_all ​− BIO allocation and freeing functions

SYNOPSIS​ #include <openssl/bio.h> ​ ​ BIO * BIO_new(const BIO_METHOD *type); ​ int BIO_up_ref(BIO *a); ​ int BIO_free(BIO *a); ​ void BIO_vfree(BIO *a); ​ void BIO_free_all(BIO *a);

DESCRIPTIONThe BIO_new() function returns a new BIO using method type. BIO_up_ref() increments the reference count associated with the BIO object. BIO_free() frees up a single BIO, BIO_vfree() also frees up a single BIO but it does not return a value. If a is NULL nothing is done. Calling BIO_free() may also have some effect on the underlying I/O structure, for example it may close the file being referred to under certain circumstances. For more details see the individual ​BIO_METHOD descriptions. BIO_free_all() frees up an entire BIO chain, it does not halt if an error occurs freeing up an individual BIO in the chain. If a is NULL nothing is done.

RETURN VALUESBIO_new() returns a newly created BIO or NULL if the call fails. BIO_up_ref() and BIO_free() return 1 for success and 0 for failure. BIO_free_all() and BIO_vfree() do not return values.

NOTESIf BIO_free() is called on a BIO chain it will only free one BIO resulting in a memory leak. Calling BIO_free_all() on a single BIO has the same effect as calling BIO_free() on it other than the discarded return value.

HISTORYBIO_set() was removed in OpenSSL 1.1.0 as BIO type is now opaque.

EXAMPLESCreate a memory BIO: ​ BIO *mem = BIO_new(BIO_s_mem());
