+Function silc_asn1_encode
+
+
+SYNOPSIS
+
+
+ SilcBool silc_asn1_encode(SilcAsn1 asn1, SilcBuffer dest, ...);
+
+
+DESCRIPTION
+
+
+ Encodes ASN.1 encoded buffer into `dest', from variable argument
+ list of ASN.1 types. The variable argument list forms the ASN.1
+ trees and nodes that are encoded into the `dest'. By default, the
+ memory for `dest' is allocated from the `asn1', and the buffer becomes
+ invalid either by calling silc_asn1_free, silc_asn1_uninit, or when
+ silc_asn1_encode is called for the next time.
+
+ If the SILC_ASN1_OPTS macro with SILC_ASN1_ALLOC option is given then
+ the `dest' is dynamically allocated and caller must free it by itself.
+ Alternatively if SILC_ASN1_ACCUMUL is given then memory is accumulated
+ from `asn1' for `dest' and it is freed only when silc_asn1_free or
+ silc_asn1_uninit is called. Next call to silc_asn1_encode will not
+ cancel the previous result, but will accumulate more memory for new
+ result.
+
+ The variable argument list is constructed by using various
+ macros, for example SILC_ASN1_SEQUENCE, etc. The variable argument
+ list must always be ended with SILC_ASN1_END type.
+
+ If encoding is successful this returns TRUE, FALSE on error.
+
+
+EXAMPLE
+
+
+ silc_asn1_encode(asn1, buf,
+ SILC_ASN1_SEQUENCE,
+ SILC_ASN1_BOOLEAN(bool_val),
+ SILC_ASN1_OCTET_STRING(string, string_len),
+ SILC_ASN1_SEQUENCE_T(0, 2),
+ SILC_ASN1_BOOLEAN_T(SILC_ASN1_EXPLICIT, 100, foo),
+ SILC_ASN1_END,
+ SILC_ASN1_OCTET_STRING_T(0, 1, string2, string2_len),
+ SILC_ASN1_END, SILC_ASN1_END);
+
+ Creates ASN.1 tree that looks something like:
+
+ buf ::= SEQUENCE {
+ bool_val BOOLEAN,
+ string OCTET-STRING,
+ [2] SEQUENCE {
+ foo [100] EXPLICIT BOOLEAN }
+ string2 [1] OCTET-STRING }
