ber_put_null - Linux

Overview

ber_put_null writes a BER-encoded NULL value to a BER element.

Syntax

ber_put_null(ber_element *ber, int ber_class, int ber_type, const char *ber_opt_identifier)

Options/Flags

• ber_class: BER class for the element.
• ber_type: BER type for the element.
• ber_opt_identifier: Identifier for the element.

Examples

Writing a NULL value to a BER sequence

#include <ber.h>
#include <stdio.h>

int main() {
    ber_element *ber = ber_alloc();
    ber_printf(ber, "{t}", NULL);
    printf("BER-encoded NULL value: %s\n", ber_buffer(ber));
    ber_free(ber);
    return 0;
}

Writing a NULL value with an identifier.

#include <ber.h>
#include <stdio.h>

int main() {
    ber_element *ber = ber_alloc();
    ber_printf(ber, "{t:i}", "my_null", NULL);
    printf("BER-encoded NULL value with identifier: %s\n", ber_buffer(ber));
    ber_free(ber);
    return 0;
}

Common Issues

None.

Integration

ber_put_null can be used with other BER functions to encode complex BER structures.
