Like ASN1_mbstring_copy(), also enforcing minimum and maximum character counts.

Synopsis

Declared in <openssl/asn1.h>

int
ASN1_mbstring_ncopy(
    ASN1_STRING** out,
    unsigned char const* in,
    int len,
    int inform,
    unsigned long mask,
    long minsize,
    long maxsize);

Return Value

Positive ASN.1 string type on success, or a negative value on error.

Parameters

Name

Description

out

Destination; if NULL a new string is allocated, otherwise *`out` may be reused.

in

Input bytes in the encoding given by inform.

len

Length of in in bytes, or ‐1 if in is NUL‐terminated.

inform

Input encoding (MBSTRING_ASC, MBSTRING_BMP, MBSTRING_UNIV, or MBSTRING_UTF8).

mask

B_ASN1_* bitmask of permitted output string types (0 selects the default mask).

minsize

Minimum character count (0 disables the check).

maxsize

Maximum character count (0 disables the check).
