| void ldns_buffer_new_frm_data | ( | ldns_buffer * | buffer, |
| const void * | data, | ||
| size_t | size | ||
| ) |
creates a buffer with the specified data.
The data IS copied and MEMORY allocations are done. The buffer is not fixed and can be resized using buffer_reserve().
| [in] | buffer | pointer to the buffer to put the data in |
| [in] | data | the data to encapsulate in the buffer |
| [in] | size | the size of the data |

| signed char ldns_buffer_set_capacity | ( | ldns_buffer * | buffer, |
| size_t | 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.
| [in] | buffer | the buffer |
| [in] | capacity | the capacity to use |
| signed char ldns_buffer_reserve | ( | ldns_buffer * | buffer, |
| size_t | amount | ||
| ) |
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.
| [in] | buffer | the buffer |
| [in] | amount | amount to use |

| void ldns_buffer_free | ( | ldns_buffer * | buffer | ) |
frees the buffer.
| [in] | *buffer | the buffer to be freed |

| void* ldns_buffer_export | ( | ldns_buffer * | buffer | ) |
Makes the buffer fixed and returns a pointer to the data.
The caller is responsible for free'ing the result.
| [in] | *buffer | the buffer to be exported |

| int ldns_bgetc | ( | ldns_buffer * | buffer | ) |
returns the next character from a buffer.
Advances the position pointer with 1. When end of buffer is reached returns EOF. This is the buffer's equivalent for getc().
| [in] | *buffer | buffer to read from |
| void ldns_buffer_copy | ( | ldns_buffer * | result, |
| const ldns_buffer * | from | ||
