mbedtls_asn1_write_oid() function

Write an OID tag (#MBEDTLS_ASN1_OID) and data in ASN.1 format.

Syntax

int mbedtls_asn1_write_oid( unsigned char **p,     unsigned char *start,     const char *oid,     size_t oid_len );
Implemented in asn1write.c:182

Arguments

p

The reference to the current position pointer.

start

The start of the buffer, for bounds-checking.

oid

The OID to write.

oid_len

The length of the OID.

Return value

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

Notes

This function works backwards in data buffer.
