Subject [jira] [Commented] (HDFS-9368) Implement reads with implicit offset state in libhdfs++
Date Wed, 18 Nov 2015 21:12:10 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9368?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15011974#comment-15011974
] 

Haohui Mai commented on HDFS-9368:
----------------------------------

{code}
+  Status Pread(void *buf, size_t *nbyte /* in/out */, off_t offset);
+  Status Read(void *buf, size_t *nbyte /* in/out */);
+  Status Seek(off_t *offset /* in/out */, std::ios_base::seekdir whence);
{code}

What about getting rid of the {{in/out}} annotation and putting some comments for each function?
+1 after addressing it.

> Currently only positional reads are supported.  Implement a stateful read that keeps
track of offset into file.  Also expose it in the c bindings as hdfsRead.
