=head1 NAME
|
|
|
|
SSL_free_buffers, SSL_alloc_buffers - manage SSL structure buffers
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/ssl.h>
|
|
|
|
int SSL_free_buffers(SSL *ssl);
|
|
int SSL_alloc_buffers(SSL *ssl);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
SSL_free_buffers() frees the read and write buffers of the given B<ssl>.
|
|
SSL_alloc_buffers() allocates the read and write buffers of the given B<ssl>.
|
|
|
|
The B<SSL_MODE_RELEASE_BUFFERS> mode releases read or write buffers whenever
|
|
the buffers have been drained. These functions allow applications to manually
|
|
control when buffers are freed and allocated.
|
|
|
|
After freeing the buffers, the buffers are automatically reallocated upon a
|
|
new read or write. The SSL_alloc_buffers() does not need to be called, but
|
|
can be used to make sure the buffers are preallocated. This can be used to
|
|
avoid allocation during data processing or with CRYPTO_set_mem_functions()
|
|
to control where and how buffers are allocated.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
The following return values can occur:
|
|
|
|
=over 4
|
|
|
|
=item 0 (Failure)
|
|
|
|
The SSL_free_buffers() function returns 0 when there is pending data to be
|
|
read or written. The SSL_alloc_buffers() function returns 0 when there is
|
|
an allocation failure.
|
|
|
|
=item 1 (Success)
|
|
|
|
The SSL_free_buffers() function returns 1 if the buffers have been freed. This
|
|
value is also returned if the buffers had been freed before calling
|
|
SSL_free_buffers().
|
|
The SSL_alloc_buffers() function returns 1 if the buffers have been allocated.
|
|
This value is also returned if the buffers had been allocated before calling
|
|
SSL_alloc_buffers().
