Detailed Description

Mode-S transponder Binary Data Source (BDS) register processing.

Macro Definition Documentation

◆ AST_BDS_DETAIL_HTML_PREFERED_CHARS

#define AST_BDS_DETAIL_HTML_PREFERED_CHARS 20480

Prefered number of chars of BDS detail description HTML snippet.

◆ AST_BDS_SIZE

#define AST_BDS_SIZE 7

BDS bytes.

◆ AST_MAP_BDS_TYPE

#define AST_MAP_BDS_TYPE	(		msb,
			lsb )

Value:

BDS ## msb ## lsb = 0x ## msb ## lsb,

Macro used to map BDS type.

A BDS type is an enum value like BDS40, and it's value will be 0x40.

◆ AST_MAX_BDS

#define AST_MAX_BDS 8

Max number of BDS in one data item.

Enumeration Type Documentation

◆ ast_bds_type_t

enum ast_bds_type_t

Function Documentation

◆ ast_bds_decode()

ast_bds_t ast_bds_decode	(	const unsigned char *	buffer,
		const size_t	bufsize,
		const ast_bds_type_t	type )

Decode BDS from binary data.

◆ ast_bds_get_detail_html()

void ast_bds_get_detail_html	(	char *	detail,
		const size_t	detail_size,
		const ast_bds_t	bds )

Function to get a html snippet of detailed description of dataitem.

Parameters

detail	Buffer to save the html snippet
detail_size	Buffer size
bds	BDS

The returned html fragment contains only basic elements used in html body, such as <br/> <h> <table>....

This function will return only semantics markups, some elements will cantaion class name, and it's recomanded the libary user to use CSS to format the html style.

◆ ast_bds_get_detail_html_dummy()

void ast_bds_get_detail_html_dummy	(	char *	detail,
		const size_t	detail_size,
		const ast_bds_t	bds )

Dummy get detail function.

For some data items, it's not necesary to implement a get_detail_html function. In this case, the dataitem's get_detail_html_func can be register to this dummy function. It' will only set detail as a NULL string and do nothing else.

◆ ast_bds_get_name()

const char * ast_bds_get_name ( const ast_bds_type_t type )

Function to get name of one BDS.

Name is the title of each BDS defined in RTCA documentation

◆ ast_bds_type_to_str()

const char * ast_bds_type_to_str ( const ast_bds_type_t type )

Convert from ast_bds_type_t to C string.

Returns: string like "BDS4,0";

Here is the call graph for this function:

◆ ast_bds_type_to_str_simple()

const char * ast_bds_type_to_str_simple ( const ast_bds_type_t type )

Convert from ast_bds_type_t to C string simple version.

Returns: string like "4,0";
