Preferred number of chars of dataitem binary HTML snippet.

◆ AST_DATAITEM_BIN_STR_PREFERED_CHARS

#define AST_DATAITEM_BIN_STR_PREFERED_CHARS   (AST_MAX_DATAITEM_SIZE * 9)

Preferred number of chars of dataitem binary string.

◆ AST_DATAITEM_DETAIL_HTML_PREFERED_CHARS

#define AST_DATAITEM_DETAIL_HTML_PREFERED_CHARS   (AST_DATAITEM_HEX_HTML_PREFERED_CHARS + AST_DATAITEM_BIN_HTML_PREFERED_CHARS + 20480)

Preferred number of chars of data item detail description HTML snippet.

◆ AST_DATAITEM_HEX_HTML_PREFERED_CHARS

#define AST_DATAITEM_HEX_HTML_PREFERED_CHARS   (AST_MAX_DATAITEM_SIZE * 12 + 128)

Preferred number of chars of dataitem hexadecimal HTML snippet.

◆ AST_DATAITEM_HEX_STR_PREFERED_CHARS

#define AST_DATAITEM_HEX_STR_PREFERED_CHARS   (AST_MAX_DATAITEM_SIZE * 3)

Preferred number of chars of dataitem hexadecimal string.

Examples
example.c.

◆ AST_DATAITEM_SUMMARY_PREFERED_CHARS

#define AST_DATAITEM_SUMMARY_PREFERED_CHARS   256

Preferred number of chars of dataitem summary.

Examples
example.c.

◆ AST_MAP_DATAITEM_TYPE_EX

#define AST_MAP_DATAITEM_TYPE_EX ( category_name,
category_value,
dataitem_name,
dataitem_value )
Value:
I ## category_name ## _ ## dataitem_name = category_value ## dataitem_value,

Macro used to map data item type.

A data item type is an enum value like I062_380, and its value will be 62 * 1000 + 380 = 62380.

Warning
As in C, a value starting with 0 will be treated as octal, the category number shall not contain the preceding 0.

◆ AST_MAX_DATAITEM_SIZE

#define AST_MAX_DATAITEM_SIZE   1024

Max data item bytes.

◆ REF

#define REF   998

Reserved expansion field (REF) maps to 998

◆ RFS

#define RFS   997

Random field sequencing (RFS) maps to 997

◆ SPF

#define SPF   999

Special data items SPF, REF and RFS are widely used in different categories by different manufacturers.

Special purpose field (SPF) maps to 999

Enumeration Type Documentation

◆ ast_dataitem_type_t

enum ast_dataitem_type_t

Definition of data item type in each category.

Enumerator
INULLITEM 

Null (Empty) dataitem.

Function Documentation

◆ ast_dataitem_copy()

ast_dataitem_t ast_dataitem_copy ( unsigned char *const buffer,
const size_t bufsize,
const ast_dataitem_t src )

Copy data item to binary buffer.

◆ ast_dataitem_decode()

ast_dataitem_t ast_dataitem_decode ( const unsigned char * buffer,
const size_t bufsize,
const ast_dataitem_type_t type )

Decode data item from binary data.

◆ ast_dataitem_encode()

ast_dataitem_t ast_dataitem_encode ( unsigned char *const buffer,
const size_t bufsize,
const ast_dataitem_ex_t xdi )

Encode data item from extracted data.

◆ ast_dataitem_get_bin_html()

void ast_dataitem_get_bin_html ( char * html,
const size_t html_size,
const ast_dataitem_t di )

Function to get a html snippet of the raw data item data in binary format.

The return text will be an html table with data in the cells.

◆ ast_dataitem_get_bin_str()

void ast_dataitem_get_bin_str ( char * string,
const size_t string_size,
const ast_dataitem_t di )

Function to get raw data item data in binary format.

There will be a space between each byte. E.g. "10011111 10100110 10001111"

◆ ast_dataitem_get_detail_html()

void ast_dataitem_get_detail_html ( char * detail,
const size_t detail_size,
const ast_dataitem_t di )

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

Parameters
detailBuffer to save the html snippet
detail_sizeBuffer size
diDataitem

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 contain class name, and it is recommended for the library user to use CSS to format the html style.
