PSA_MAC_OPERATION_INIT

#define PSA_MAC_OPERATION_INIT   { 0 }

This macro returns a suitable initializer for a MAC operation object of type psa_mac_operation_t.

Typedef Documentation

psa_mac_operation_t

typedef struct psa_mac_operation_s psa_mac_operation_t

The type of the state object for multi-part MAC operations.

Before calling any function on a MAC operation object, the application must initialize it by any of the following means:

• Set the object to all-bits-zero, for example:

  @ref psa_mac_operation_t operation;
  memset(&operation, 0, sizeof(operation));

• Initialize the object to logical zero values by declaring the object as static or global without an explicit initializer, for example:

  static @ref psa_mac_operation_t operation;

• Initialize the object to the initializer PSA_MAC_OPERATION_INIT, for example:

  @ref psa_mac_operation_t operation = @ref PSA_MAC_OPERATION_INIT;

• Assign the result of the function psa_mac_operation_init() to the object, for example:

  @ref psa_mac_operation_t operation;
  operation = @ref psa_mac_operation_init();

  This is an implementation-defined type. Applications that make assumptions about the content of this object will result in in implementation-specific behavior, and are non-portable.
