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.

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
