Context or codec state. The state field in rte_context and rte_codec must be set by the context and codec functions as documented below.

Sets the context error string. |
|
Sets the context error string. |
|
Identical to GNU or BSD libc asprintf(). |
|
Same as the libc strdup(), except for d argument and setting the context error string on failure.

Find in a vector of int values the entry closest to val and return its index, 0 ... n.

|
Find in a vector of double values the entry closest to val and return its index, 0 ... n.
