Detailed Description

Some general information about the compressor.

The structure is used by the rohc_comp_get_general_info function to store some general information about the compressor.

Versioning works as follow:

• The version_major field defines the compatibility level. If the major number given by user does not match the one expected by the library, an error is returned.
• The version_minor field defines the extension level. If the minor number given by user does not match the one expected by the library, only the fields supported in that minor version will be filled by rohc_comp_get_general_info.

Notes for developers:

• Increase the major version if a field is removed.
• Increase the major version if a field is added at the beginning or in the middle of the structure.
• Increase the minor version if a field is added at the very end of the structure.
• The version_major and version_minor fields must be located at the very beginning of the structure.
• The structure must be packed.

Supported versions:

• major 0 and minor = 0 contains: version_major, version_minor, contexts_nr, packets_nr, uncomp_bytes_nr, and comp_bytes_nr.
