Function Documentation

ec_foe_request_init()

void ec_foe_request_init	(	ec_foe_request_t *	req,
		uint8_t *	file_name )

FoE request constructor.

Parameters

req	FoE request.
file_name	filename

Definition at line 52 of file foe_request.c.

ec_foe_request_clear()

void ec_foe_request_clear

(

ec_foe_request_t *

req

)

FoE request destructor.

Parameters

req	FoE request.

Definition at line 73 of file foe_request.c.

ec_foe_request_alloc()

int ec_foe_request_alloc	(	ec_foe_request_t *	req,
		size_t	size )

Pre-allocates the data memory.

If the internal buffer_size is already bigger than size, nothing is done.

Returns

Zero on success, otherwise a negative error code.

Parameters

req	FoE request.
size	Data size to allocate.

Definition at line 106 of file foe_request.c.

ec_foe_request_copy_data()

int ec_foe_request_copy_data	(	ec_foe_request_t *	req,
		const uint8_t *	source,
		size_t	size )

Copies FoE data from an external source.

If the buffer_size is to small, new memory is allocated.

Returns

Zero on success, otherwise a negative error code.

Parameters

req	FoE request.
source	Source data.
size	Number of bytes in source.

Definition at line 135 of file foe_request.c.

ec_foe_request_timed_out()

int ec_foe_request_timed_out

(

const ec_foe_request_t *

req

)

Checks, if the timeout was exceeded.

Returns

non-zero if the timeout was exceeded, else zero.

Parameters

req	FoE request.

Definition at line 159 of file foe_request.c.

ec_foe_request_write()

void ec_foe_request_write

(

ec_foe_request_t *

req

)

Prepares a write request (master to slave).

Parameters

req	FoE request.

Definition at line 185 of file foe_request.c.

ec_foe_request_read()

void ec_foe_request_read

(

ec_foe_request_t *

req

)

Prepares a read request (slave to master).

Parameters

req	FoE request.
