/**
* Special case function for registering a VFS that uses a method other than
* open() to open new file descriptors from the interval <min_fd; max_fd).
*
* This is a special-purpose function intended for registering LWIP sockets to VFS.
*
* @param vfs Pointer to esp_vfs_fs_ops_t. Meaning is the same as for esp_vfs_register_fs().
* @param ctx Pointer to context structure. Meaning is the same as for esp_vfs_register_fs().
* @param min_fd The smallest file descriptor this VFS will use.
* @param max_fd Upper boundary for file descriptors this VFS will use (the biggest file descriptor plus one).
*
* @return ESP_OK if successful,
* ESP_ERR_NO_MEM if too many VFSes are registered,
* ESP_ERR_INVALID_ARG if the file descriptor boundaries are incorrect.
