xmlSecSize
xmlSecBufferGetMaxSize (xmlSecBufferPtr buf);

Gets the maximum (allocated) buffer size.

xmlSecBufferSetMaxSize ()

int
xmlSecBufferSetMaxSize (xmlSecBufferPtr buf,
                        xmlSecSize size);

Sets new buffer maximum size. If necessary, buffer grows to have at least size bytes.

xmlSecBufferEmpty ()

void
xmlSecBufferEmpty (xmlSecBufferPtr buf);

Empties the buffer.

xmlSecBufferSwap ()

void
xmlSecBufferSwap (xmlSecBufferPtr buf1,
                  xmlSecBufferPtr buf2);

Swaps the content of the two buffers.

xmlSecBufferAppend ()

int
xmlSecBufferAppend (xmlSecBufferPtr buf,
                    const xmlSecByte *data,
                    xmlSecSize size);

Appends the data after the current data stored in the buffer.

xmlSecBufferPrepend ()

int
xmlSecBufferPrepend (xmlSecBufferPtr buf,
                     const xmlSecByte *data,
                     xmlSecSize size);

Prepends the data before the current data stored in the buffer.

xmlSecBufferRemoveHead ()

int
xmlSecBufferRemoveHead (xmlSecBufferPtr buf,
                        xmlSecSize size);

Removes size bytes from the beginning of the current buffer.

xmlSecBufferRemoveTail ()

int
xmlSecBufferRemoveTail (xmlSecBufferPtr buf,
                        xmlSecSize size);

Removes size bytes from the end of current buffer.

xmlSecBufferReverse ()

int
xmlSecBufferReverse (xmlSecBufferPtr buf);

Reverses order of bytes in the buffer buf .

xmlSecBufferReadFile ()

int
xmlSecBufferReadFile (xmlSecBufferPtr buf,
                      const char *filename);

Reads the content of the file filename in the buffer.

xmlSecBufferBase64NodeContentRead ()

int
xmlSecBufferBase64NodeContentRead (xmlSecBufferPtr buf,
                                   xmlNodePtr node);

Reads the content of the node , base64 decodes it and stores the result in the buffer.

xmlSecBufferBase64NodeContentWrite ()

int
xmlSecBufferBase64NodeContentWrite (xmlSecBufferPtr buf,
                                    xmlNodePtr node,
