#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_mavlink_schema_builder_extension(

) -> PamojaStatus
Expand description

Adds a MAVLink 2 extension field, in the order the definition declares it.

Extensions keep their declared order, stay out of the CRC_EXTRA seed, and read as zero from a frame sent by a peer that predates them.

§Arguments

  • builder - the description to extend.
  • name - the field name.
  • field_type - the field’s type, one of the PAMOJA_MAVLINK_FIELD_* codes.
  • array_len - the element count for an array, or 0 for a scalar.

§Returns

PamojaStatus::Ok on success.

§Errors

Returns PamojaStatus::InvalidArgument if a pointer is null, name is not UTF-8, or field_type is not a MAVLink field type.

§Safety

builder must be a live builder handle and name a null-terminated C string.
