libnvmf_context_set_devid_file(9)                           libnvme API manual

NAME
       libnvmf_context_set_devid_file - Set devid file for context

SYNOPSIS
       int libnvmf_context_set_devid_file (struct libnvmf_context *fctx ,
       const char *devid_file );

ARGUMENTS
       fctx        Fabrics context

       devid_file  Path to the output file

DESCRIPTION
       Configure a file that libnvmf_connect uses to record the kernel-
       assigned device name (for example, "nvme0").

       If the controller is already connected, the existing device name is
       written. Otherwise, the device name is written after the controller is
       connected.

       The output file is created before attempting the connection. If the
       file cannot be created, for example because the parent directory does
       not exist, libnvmf_connect fails without attempting the connection.

       This is intended for applications that need to identify the device
       associated with a connection, for example to disconnect it later.

RETURN
       0 on success, negative error code otherwise.
