NAME

ASN1_X509_MODE ASN1_DER_MODE ASN1_CER_MODE asn1_unique asn1_std_mode_on asn1_x509_mode_on

SYNOPSIS


area_end = XXXXXX_cod(area, scope, ASN1_DER_MODE|num, argument_list);


area_end = XXXXXX_cod(area, scope, ASN1_X509_MODE|num, argument_list);


area_end = XXXXXX_cod(area, scope, ASN1_CER_MODE|num, argument_list);

DESCRIPTION



The coding routines generated by MAVROS can be parametrized to provide unique
encodings, as required by e.g. security applications. This encoding can be
selected at run time. Using the flags 
ASN1_DER_MODE
or
ASN1_X509_MODE
results in the ASN.1 "distinguished encoding rules", as specified in e.g. the
X.509 recommendation. Using the flag
ASN1_CER_MODE
results in the ASN.1 "canonical encoding rules", which are a different way to
obtain "unique" encodings of ASN.1 specified data. A detailed description
can be found in the 
mavros-output
manual pages.


The procedures
asn1_x509_mode_on()
and
asn1_std_mode_on()
which were found in a previous release of the MAVROS compiler are no longer
available.
