uint8_t * ldns_buffer_current(ldns_buffer *buffer);

DESCRIPTION

ldns_buffer_limit(): returns the maximum size of the buffer \param[in] buffer .br Returns the size

ldns_buffer_set_limit(): changes the buffer's limit. If the buffer's position is greater than the new limit the position is set to the limit. .br buffer: the buffer .br limit: the new limit

ldns_buffer_capacity(): returns the number of bytes the buffer can hold. .br buffer: the buffer .br Returns the number of bytes

ldns_buffer_set_capacity(): changes the buffer's capacity. The data is reallocated so any pointers to the data may become invalid. The buffer's limit is set to the buffer's new capacity. .br buffer: the buffer .br capacity: the capacity to use .br Returns whether this failed or succeeded

ldns_buffer_reserve(): ensures BUFFER can contain at least AMOUNT more bytes. The buffer's capacity is increased if necessary using buffer_set_capacity().
The buffer's limit is always set to the (possibly increased) capacity. .br buffer: the buffer .br amount: amount to use .br Returns whether this failed or succeeded

ldns_buffer_at(): returns a pointer to the data at the indicated position. .br buffer: the buffer .br at: position .br Returns the pointer to the data

ldns_buffer_begin(): returns a pointer to the beginning of the buffer (the data at position 0). .br buffer: the buffer .br Returns the pointer

ldns_buffer_end(): returns a pointer to the end of the buffer (the data at the buffer's limit). .br buffer: the buffer .br Returns the pointer

ldns_buffer_current(): returns a pointer to the data at the buffer's current position. .br buffer: the buffer .br Returns the pointer
