NAME

       fmt_asn1dertag - encode unsigned integer like ASN.1 DER tag

SYNTAX

       #include <fmt.h>

       size_t fmt_asn1dertag(char *dest,unsigned long long source);

DESCRIPTION

       fmt_asn1dertag encodes an unsigned integer using the ASN.1 DER for encoding tag.  This takes one byte for
       every 7 bits in the number.

       If dest equals FMT_LEN (i.e. is NULL), fmt_asn1dertag returns the number of bytes it would have written.

       For convenience, fmt.h defines the integer FMT_ASN1TAG  to  be  big  enough  to  contain  every  possible
       fmt_asn1dertag output.
