gnutls_compression_get - Linux

Overview

The gnutls_compression_get function in GnuTLS retrieves the currently set compression algorithm.

Syntax

#include <gnutls/gnutls.h>

int gnutls_compression_get(gnutls_session_t session,
                           const gnutls_datum_t *data);

Options/Flags

The following options are supported:

• session: The GnuTLS session.

• data: The compression algorithm (output):

  • For GnuTLS_COMP_NULL: NULL
  • For GnuTLS_COMP_DEFLATE: "DEFLATE"
  • For GnuTLS_COMP_ZLIB: "ZLIB"

Examples

#include <stdio.h>
#include <gnutls/gnutls.h>
int main() {
  gnutls_session_t session = NULL;
  gnutls_datum_t data;
  gnutls_compression_get(session, &data);
  printf("The compression algorithm is: %s\n", data.data);
  return 0;
}

Common Issues

• If the session is not initialized, the function will return -1.
• If the compression algorithm is not set, the function will return -1.

Integration

The gnutls_compression_get function can be used with other GnuTLS functions to manage compression in a TLS session.
