# [SYNOPSIS](#SYNOPSIS)

struct nvme\_exported\_subsys\_mgmt\_data {  
**\_\_u8 rsvd0\[64];**  
**\_\_le16 numhent;**  
**\_\_le16 numense;**  
**\_\_u8 rsvd68\[188];**

[entries](#entries)

*numhent* entries of *struct nvme\_exported\_subsys\_mgmt\_host\_entry* followed by *numense* entries of *struct* *nvme\_exported\_subsys\_mgmt\_subsys\_entry*. Left as a raw byte buffer since the two variable-length lists have different element sizes and cannot both be expressed as fixed struct members - the caller walks *entries* using the sizes of those two struct types.
