# [NAME](#NAME)

ASN1\_BIT\_STRING\_new, ASN1\_BIT\_STRING\_free - ASN1\_BIT\_STRING allocation functions

# [SYNOPSIS](#SYNOPSIS)

```
 #include <openssl/asn1.h>
 ASN1_BIT_STRING *ASN1_BIT_STRING_new(void);
 void ASN1_BIT_STRING_free(ASN1_BIT_STRING *a);
```

# [DESCRIPTION](#DESCRIPTION)

**ASN1\_BIT\_STRING\_new()** returns an allocated **ASN1\_BIT\_STRING** structure.

**ASN1\_BIT\_STRING\_free()** frees up a single **ASN1\_BIT\_STRING** object. If the argument is NULL, nothing is done.

**ASN1\_BIT\_STRING** structure representing the ASN.1 BIT\_STRING type.

# [RETURN VALUES](#RETURN_VALUES)

**ASN1\_BIT\_STRING\_new()** return a valid **ASN1\_BIT\_STRING** structure or NULL if an error occurred.

**ASN1\_BIT\_STRING\_free()** does not return a value.
