Implemented in asn1write.c:189

Arguments

Argument

Description

The reference to the current position pointer.

start

The start of the buffer, for bounds-checking.

oid

The OID of the algorithm to write.

oid_len

The length of the algorithm's OID.

par_len

The length of the parameters, which must be already written.

has_par

If there are any parameters. If 0, par_len must be 0. If 1 and \p par_len is 0, NULL parameters are added.

Return value

The number of bytes written to \p p on success. A negative \c MBEDTLS_ERR_ASN1_XXX error code on failure.
