Function Documentation

fpa1_syntaxList* fpa1_parseScriptASN	(	unsigned char *	asndata,
		unsigned long	len
	)

Top level entry point to the ASN.1 script to fpa1_syntaxList converter. This function takes the original ASN.1 script as a character array and returns a pointer to a syntax list representing the contents of the ASN.1 script.

Parameters

asndata	ASN.1 script (as character array)
len	Length of asn.1 script.

Returns

*fpa1_syntaxList
