Macro Definition Documentation

PSA_HASH_OPERATION_INIT

#define PSA_HASH_OPERATION_INIT   { 0 }

This macro returns a suitable initializer for a hash operation object of type psa_hash_operation_t.

Typedef Documentation

psa_hash_operation_t

typedef struct psa_hash_operation_s psa_hash_operation_t

The type of the state data structure for multipart hash operations.

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

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

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

• Initialize the structure to logical zero values, for example:

  @ref psa_hash_operation_t operation = {0};

• Initialize the structure to the initializer PSA_HASH_OPERATION_INIT, for example:

  @ref psa_hash_operation_t operation = @ref PSA_HASH_OPERATION_INIT;

• Assign the result of the function psa_hash_operation_init() to the structure, for example:

  @ref psa_hash_operation_t operation;
  operation = @ref psa_hash_operation_init();

This is an implementation-defined struct. Applications should not make any assumptions about the content of this structure except as directed by the documentation of a specific implementation.
