Summary

Declaration

Definition

from asn1write.h:336

int mbedtls_asn1_write_named_bitstring(unsigned char **p, const unsigned char *start, const unsigned char *buf, size_t bits);

Implemented in asn1write.c:266

Arguments

Argument

Description

The reference to the current position pointer.

start

The start of the buffer which is used for bounds-checking.

buf

The bitstring to write.

bits

The total number of bits in the bitstring.

Return value

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

Notes
