A DBUF_MEM_new.pod11 #include <openssl/buffer.h>
26 The buffer library handles simple character arrays. Buffers are used for
29 BUF_MEM_new() allocates a new buffer of zero size.
31 BUF_MEM_new_ex() allocates a buffer with the specified flags.
35 BUF_MEM_free() frees up an already existing buffer. The data is zeroed
36 before freeing up in case the buffer contains sensitive data.
38 BUF_MEM_grow() changes the size of an already existing buffer to
39 B<len>. Any data already in the buffer is preserved if it increases in
50 BUF_MEM_new() returns the buffer or NULL on error.
A DBIO_f_buffer.pod31 an internal buffer which is filled from the next BIO in the chain.
39 set the read, write or both read and write buffer sizes to B<size>. The initial
40 buffer size is DEFAULT_BUFFER_SIZE, currently 4096. Any attempt to reduce the
41 buffer size below DEFAULT_BUFFER_SIZE is ignored. Any buffered data is cleared
42 when the buffer is resized.
44 BIO_set_buffer_read_data() clears the read buffer and fills it with B<num>
45 bytes of B<buf>. If B<num> is larger than the current buffer size the buffer
54 result in an internal buffer, from which bytes are given back to the
64 doing so will force a full read of the size of the internal buffer of

A DBIO_s_bio.pod50 buffer is full.
53 determine the amount of pending data in the read or write buffer.
55 BIO_reset() clears any data in the write buffer.
71 BIO_get_write_buf_size() returns the size of the write buffer.
75 with write buffer sizes B<writebuf1> and B<writebuf2>. If either size is
87 amount of data requested, or the buffer size if it is less, if the
89 empty buffer. This can be used to determine how much data should be
92 meaningful rather than just a buffer size. After a successful read
171 buffer is full or the read buffer is drained. Then the application has to
172 flush the write buffer and/or fill the read buffer.

A DEVP_PKEY_get_size.pod27 also large enough for the output buffer of L<EVP_PKEY_sign(3)>,
33 contents of the target buffer may be smaller. It is therefore crucial

54 buffer and still pass a pointer to an integer and get the exact size

A DBIO_f_readbuffer.pod21 Data read from a read buffering BIO comes from an internal buffer which is
33 internal buffer, from which bytes are given back to the caller as appropriate
36 next BIO. The internal buffer can grow to cache the entire contents of the next
37 BIO in the chain. BIO_seek() uses the internal buffer, so that it can only seek
A DEVP_PKEY_CTX_set_hkdf_md.pod74 buffer B<salt>. Any existing value is replaced.
76 EVP_PKEY_CTX_set1_hkdf_key() sets the key to B<keylen> bytes of the buffer
80 buffer B<info>. If a value is already set, it is appended to the existing
102 The total length of the info buffer cannot exceed 1024 bytes in length: this
107 Since the HKDF output length is variable, passing a B<NULL> buffer as a means
109 performs an expand operation. Instead, the caller must allocate a buffer of the
110 desired length, and pass that buffer to L<EVP_PKEY_derive(3)> along with (a
111 pointer initialized to) the desired length. Passing a B<NULL> buffer to obtain
