18 * @buffer: The data buffer.
19 * @offset: Our current position in the buffer.
20 * @size: The size of the data buffer.
29 * buffer_fetchchar - Fetches a char from a buffer.
30 * @ctx: Our buffer context structure.
31 * @count: The number of characters to get from the buffer.
32 * @c: Where to put the characters retrieved.
34 int buffer_fetchchar(void *ctx, size_t count, unsigned char *c);
37 * buffer_putchar - Puts a char to a buffer.
38 * @ctx: Our buffer context structure.
39 * @count: The number of characters to put into the buffer.
40 * @c: The characters to add to the buffer.
42 * Adds characters to the buffer references by the buffer context. If we
43 * fill it then we double the size of the current buffer and then add the
