typedef uint32_t bitmap4<>;
+---------------+---------------------------------------------------+
| Data Type | Definition |
+---------------+---------------------------------------------------+
| int32_t | typedef int int32_t; |
| uint32_t | typedef unsigned int uint32_t; |
| int64_t | typedef hyper int64_t; |
| uint64_t | typedef unsigned hyper uint64_t; |
| attrlist4 | typedef opaque attrlist4<>; |
| | Used for file/directory attributes. |
| bitmap4 | typedef uint32_t bitmap4<>; |
| | Used in attribute array encoding. |
| changeid4 | typedef uint64_t changeid4; |
| | Used in the definition of change_info4. |
| clientid4 | typedef uint64_t clientid4; |
| | Shorthand reference to client identification. |
| count4 | typedef uint32_t count4; |
| | Various count parameters (READ, WRITE, COMMIT). |
| length4 | typedef uint64_t length4; |
| | The length of a byte-range within a file. |
| mode4 | typedef uint32_t mode4; |
| | Mode attribute data type. |
| nfs_cookie4 | typedef uint64_t nfs_cookie4; |
| | Opaque cookie value for READDIR. |
| nfs_fh4 | typedef opaque nfs_fh4<NFS4_FHSIZE>; |
| | Filehandle definition. |
| nfs_ftype4 | enum nfs_ftype4; |
| | Various defined file types. |
| nfsstat4 | enum nfsstat4; |
| | Return value for operations. |
| offset4 | typedef uint64_t offset4; |

| | COMMIT). |
| qop4 | typedef uint32_t qop4; |
| | Quality of protection designation in SECINFO. |
| sec_oid4 | typedef opaque sec_oid4<>; |
| | Security Object Identifier. The sec_oid4 data |
| | type is not really opaque. Instead, it contains |
| | an ASN.1 OBJECT IDENTIFIER as used by GSS-API in |
| | the mech_type argument to GSS_Init_sec_context. |
| | See [[7](https://tools.ietf.org/html/rfc5661#ref-7 ""Generic Security Service Application Program Interface Version 2, Update 1"")] for details. |
| sequenceid4 | typedef uint32_t sequenceid4; |
| | Sequence number used for various session |
| | operations (EXCHANGE_ID, CREATE_SESSION, |
| | SEQUENCE, CB_SEQUENCE). |
| seqid4 | typedef uint32_t seqid4; |
| | Sequence identifier used for locking. |
| sessionid4 | typedef opaque sessionid4[NFS4_SESSIONID_SIZE]; |
| | Session identifier. |
| slotid4 | typedef uint32_t slotid4; |
| | Sequencing artifact for various session |
| | operations (SEQUENCE, CB_SEQUENCE). |
| utf8string | typedef opaque utf8string<>; |
| | UTF-8 encoding for strings. |
| utf8str_cis | typedef utf8string utf8str_cis; |
| | Case-insensitive UTF-8 string. |
| utf8str_cs | typedef utf8string utf8str_cs; |
| | Case-sensitive UTF-8 string. |
| utf8str_mixed | typedef utf8string utf8str_mixed; |
| | UTF-8 strings with a case-sensitive prefix and a |
| | case-insensitive suffix. |
| component4 | typedef utf8str_cs component4; |
| | Represents pathname components. |
| linktext4 | typedef utf8str_cs linktext4; |
| | Symbolic link contents ("symbolic link" is |
| | defined in an Open Group [[Section 3.372](https://tools.ietf.org/html/rfc5661#ref-14 ""<a href=") of Chapter 3 of Base Definitions of The Open Group Base Specifications Issue 6 IEEE Std 1003.1, 2004 Edition, HTML Version (www.opengroup.org), ISBN 1931624232"">14] standard). |
| pathname4 | typedef component4 pathname4<>; |
| | Represents pathname for fs_locations. |
| verifier4 | typedef opaque verifier4[NFS4_VERIFIER_SIZE]; |
| | Verifier used for various operations (COMMIT, |
| | CREATE, EXCHANGE_ID, OPEN, READDIR, WRITE) |
| | NFS4_VERIFIER_SIZE is defined as 8\. |
