Function Documentation

amiheader_create()

AMIHeader * amiheader_create	(	char *	name,
		size_t	name_size,
		char *	value,
		size_t	value_size )

Create new AMI header with given parameters. Will allocated memory for AMIHeader and return pointer to it.

Parameters

name	AMI header name
name_size	Name field size
value	AMI header value
value_size	Value field size

Returns

AMIHeader pointer to the new structure.

amiheader_destroy()

void amiheader_destroy

(

AMIHeader *

hdr

)

Destroy AMI header and free memory.

Parameters

hdr	AMI header to destroy

amiheader_find()

size_t amiheader_find	(	AMIPacket *	pack,
		const char *	name,
		char **	value )

Search header by header name. Will return header value length in packet exists otherwise -1. Will return only first found header value.

Parameters

pack	AMI packet structure pointer
name	Header name
value	String where the found value will be stored.

Returns

-1 or length of the header value

amiheader_to_str()

size_t amiheader_to_str	(	AMIHeader *	hdr,
		char *	buf )

Convert AMIHeader pstr string.

Parameters

hdr	AMI header structure pointer
buf	Header as string "Name: value\r\n"

Returns

header characters length

amipack_append()

int amipack_append	(	AMIPacket *	pack,
		char *	hdr_name,
		size_t	name_size,
		char *	hdr_value,
		size_t	value_size )

Parameters

pack	Pointer to AMI packet structure
hdr_name	AMI header name as string.
name_size	Header name size
hdr_value	AMI header value as string.
value_size	AMI header value size

Returns

-1 if error or number of headers in packet

amipack_destroy()

void amipack_destroy

(

AMIPacket *

pack

)

pack	AMI header to destroy

amipack_init()

AMIPacket * amipack_init

(

)

Initiate AMIPacket and allocate memory. AMI packet is implemented as linked list data structure.

Returns

AMIPacket pointer to the new structure.

amipack_list_append()

int amipack_list_append	(	AMIPacket *	pack,
		AMIHeader *	header )

Append AMI header to packet.

Parameters

pack	AMI packet structure pointer
header	AMI header structure pointer

Returns

-1 if error or number of headers in packet

amipack_queue_destroy()

void amipack_queue_destroy

(

AMIQueue *

queue

)

Parameters

pack	AMI packet structure pointer
pstr	AMI packet as string

Returns

pointer to AMI packet as string
