direct assignment to ble_gap_conn_params_t variable

[Joseph]

Hello Nordic support team,

Forgive me if I am asking a stupid question.

In the source file ble_conn_params.c, there is a function called ble_conn_params_init() and I found this direct assignment:

    m_preferred_conn_params = *p_init->p_conn_params;

but m_preferred_conn_params is a variable of ble_gap_conn_params_t which is a structure:

typedef struct {

uint16_t min_conn_interval;
/**< Minimum Connection Interval in 1.25 ms units, see @ref BLE_GAP_CP_LIMITS.*/

uint16_t max_conn_interval;
/**< Maximum Connection Interval in 1.25 ms units, see @ref BLE_GAP_CP_LIMITS.*/

uint16_t slave_latency;
/**< Slave Latency in number of connection events, see @ref BLE_GAP_CP_LIMITS.*/

uint16_t conn_sup_timeout;
/**< Connection Supervision Timeout in 10 ms units, see @ref BLE_GAP_CP_LIMITS.*/

} ble_gap_conn_params_t;

So why this direct assignment is possible?

Best Regards, Joseph

Well, p_conn_params is a pointer to a ble_gap_conn_params_t, so if you de-reference the pointer as the code appears to do you can assign a struct to a struct.

Thank you John for your reply.

So it is taken care by the compiler and it will be replaced by a memcpy(dest,src,size) statement, right?
