Function rmw_discovery_options_equal

Function Documentation

rmw_ret_t rmw_discovery_options_equal(const rmw_discovery_options_t *const left, const rmw_discovery_options_t *const right, bool *result)

Compare two discovery parameter instances for equality.

Equality means the automatic_discovery_range values are equal, they have the same static_peers_count value, and each entry in static_peers is evaluated as equal using strncmp.

NOTE: If the two parameter structs list the static peers in different orders then this will evaulate as NOT equal.

Parameters:

  • left – [in] - The first set of options to compare

  • right – [in] - The second set of options to compare

  • result – [out] - The result of the calculation.

Returns:

RMW_RET_OK when the input arguments are valid.

Returns:

RMW_RET_INVALID_ARGUMENT will be returned when any input is a nullptr, or if something in either struct was malformed, such as static_peers being a nullptr while static_peers_count is non-zero.
