NAME

6       fmt_asn1derlength - encode unsigned integer like ASN.1 DER length
7

SYNTAX

9       #include <fmt.h>
10
11       size_t fmt_asn1derlength(char *dest,unsigned long long source);
12

DESCRIPTION

14       fmt_asn1derlength  encodes  an unsigned integer using the ASN.1 DER for
15       encoding tag lengths.  This  can  take  from  1  byte  (0-0x7f)  up  to
16       sizeof(source)+1 bytes.
17
18       If  dest  equals  FMT_LEN (i.e. is NULL), fmt_asn1derlength returns the
19       number of bytes it would have written.
20
21       For convenience, fmt.h defines the integer  FMT_ASN1LENGTH  to  be  big
22       enough to contain every possible fmt_asn1derlength output.
