NAME¶

nbd_set_tls_certificates - set the path to the TLS certificates directory

SYNOPSIS¶

 #include <libnbd.h>
 int nbd_set_tls_certificates (struct nbd_handle *h,
                               const char *dir);

DESCRIPTION¶

Set the path to the TLS certificates directory. If not set and TLS is used then a compiled in default is used. For root this is "/etc/pki/libnbd/". For non-root this is "$HOME/.pki/libnbd" and "$HOME/.config/pki/libnbd". If none of these directories can be found then the system trusted CAs are used.

This function may be called regardless of whether TLS is supported, but will have no effect unless nbd_set_tls(3) is also used to request or require TLS.

RETURN VALUE¶

If the call is successful the function returns 0.

ERRORS¶

On error "-1" is returned.

Refer to "ERROR HANDLING" in libnbd(3) for how to get further details of the error.

The following parameters must not be NULL: "h", "dir". For more information see "Non-NULL parameters" in libnbd(3).

HANDLE STATE¶

The handle must be newly created, otherwise this call will return an error.

VERSION¶

This function first appeared in libnbd 1.0.

If you need to test if this function is available at compile time check if the following macro is defined:

 #define LIBNBD_HAVE_NBD_SET_TLS_CERTIFICATES 1

SEE ALSO¶
