Detailed Description

fixbuf IPFIX protocol library private interface.

These calls and structures are intended for the use of libfixbuf modules, and as such are not documented or guaranteed to remain stable in any way. Applications using these calls and structures may have to be modified to track changes to this interface across minor version releases of fixbuf.
