| sldns_buffer* sldns_buffer_new | ( | size_t | capacity | ) |
creates a new buffer with the specified capacity.
| [in] | capacity | the size (in bytes) to allocate for the buffer |

| void sldns_buffer_new_frm_data | ( | sldns_buffer * | buffer, |
| 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 |

| void sldns_buffer_init_frm_data | ( | sldns_buffer * | buffer, |
| void * | data, | ||
| size_t | size | ||
| ) |
Setup a buffer with the data pointed to.
No data copied, no memory allocs. The buffer is fixed.
| [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 |

| int sldns_buffer_set_capacity | ( | sldns_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 |
| int sldns_buffer_reserve | ( | sldns_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 sldns_buffer_free | ( | sldns_buffer * | buffer | ) |
frees the buffer.
| [in] | *buffer | the buffer to be freed |

| void sldns_buffer_copy | ( | sldns_buffer * | result, |
| sldns_buffer * | from | ||
| ) |
Copy contents of the from buffer to the result buffer and then flips the result buffer.
Data will be silently truncated if the result buffer is too small.
| [out] | *result | resulting buffer which is copied to. |
| [in] | *from | what to copy to result. |
