=head1 NAME
|
|
|
|
BIO_new, BIO_up_ref, BIO_free, BIO_vfree, BIO_free_all
|
|
- BIO allocation and freeing functions
|
|
|
|
=head1 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);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The BIO_new() function returns a new BIO using method B<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 B<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 B<a> is NULL nothing is done.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
BIO_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.
|
|
|
|
=head1 NOTES
|
|
|
|
If 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.
|
|
|
|
=head1 HISTORY
|
|
|
|
BIO_set() was removed in OpenSSL 1.1.0 as BIO type is now opaque.
|
|
|
|
=head1 EXAMPLE
|
|
|
|
Create a memory BIO:
|
|
|
|
BIO *mem = BIO_new(BIO_s_mem());
