tlv_next()

struct sof_tlv * tlv_next ( const struct sof_tlv * tlv )

inlinestatic

Allows to step through successive values in a sequence of TLV structures.

Parameters

tlv	Pointer to the base TLV.

Returns

struct sof_tlv* Pointer to the next TLV.

tlv_value_get()

void tlv_value_get ( const void * data, uint32_t size, uint32_t type, void ** value, uint32_t * length )

inlinestatic

Searches a sequence of TLV structures for values of the specified type.

Parameters

data	Pointer to the beginning of the TLV sequence.
size	The size of the data block containing the TLV structure sequences.
type	The type of the searched value.
value	A pointer that will point to the found value.
length	The size of the found value.

tlv_value_ptr_get()

void * tlv_value_ptr_get ( struct sof_tlv * tlv, uint32_t type )

inlinestatic

Retrieves pointer to the TLV Structure value of the specified type.

Parameters

tlv	TLV struct pointer.
type	Value type.

Returns

Value pointer

tlv_value_set()

void tlv_value_set ( struct sof_tlv * tlv, uint32_t type, uint32_t length, void * value )

inlinestatic

Fills the TLV Structure (general purpose version).

Parameters

tlv	TLV struct pointer.
type	Value type.
length	Value size.
value	Pointer to the value.

tlv_value_uint32_set()

void tlv_value_uint32_set ( struct sof_tlv * tlv, uint32_t type, uint32_t value )

inlinestatic

Fills the TLV Structure (version for 32-bit values).

Parameters

tlv	TLV struct pointer.
type	Value type.
value	The value.
