Detailed Description

The C run-time common library contains common C functions used by the low-level encode/decode functions. These functions are identified by their rt and rtx prefixes.

The categories of functions provided are as follows:

Macro Definition Documentation

#define XM_SKIP   0x08

skip to next field after parsing tag

Typedef Documentation

◆ ASN1BigInt

typedef struct ASN1BigInt ASN1BigInt

A structure used to define an ASN.1 big integer. This structure is rarely, if ever, used by client code, and will instead be used by generated code to facilitate encoding and decoding integer values that cannot fit in normal C/C++ integer types.

◆ ASN1DumpCbFunc

typedef int(* ASN1DumpCbFunc) (const char *text_p, void *cbArg_p)

ASN.1 dump utility callback function definition

Enumeration Type Documentation

◆ ASN1ActionType

An enumerated list of ASN.1 actions: encode or decode.

◆ ASN1StrType

An enumerated list of the various string types: hexadecimal, binary, and character strings.
