Detailed Description

Some information about the last compressed packet.

Some information about the last decompressed packet.

Some general information about the compressor.

Extensible version of rohc_comp_last_packet_info_t. 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_last_packet_info2.

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:
  • Minor = 0: version_major version_minor context_id is_context_init context_mode context_state context_used profile_id packet_type total_last_uncomp_size header_last_uncomp_size total_last_comp_size header_last_comp_size

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.
