fmt_asn1derlength(3)	    Library Functions Manual	    fmt_asn1derlength(3)

NAME
     fmt_asn1derlength - encode unsigned integer like ASN.1 DER length

SYNTAX
     #include <libowfat/fmt.h>

     size_t fmt_asn1derlength(char *dest,unsigned long long source);

DESCRIPTION
     fmt_asn1derlength	encodes  an unsigned integer using the ASN.1 DER for en-
     coding  tag  lengths.   This  can	take  from  1  byte   (0-0x7f)	 up   to
     sizeof(source)+1 bytes.

     If dest equals FMT_LEN (i.e. is NULL), fmt_asn1derlength returns the number
     of bytes it would have written.

     For  convenience, fmt.h defines the integer FMT_ASN1LENGTH to be big enough
     to contain every possible fmt_asn1derlength output.
