Status: Open
Priority: Low
+ Description: NuttX only supports a single file pointer so reads and writes
+ must be from the same position. This prohibits implementation
+ of behavior like that required for fopen() with the "a+" mode.
+ According to the fopen man page:
+
+ "a+ Open for reading and appending (writing at end of file).
+ The file is created if it does not exist. The initial file
+ position for reading is at the beginning of the file, but
+ output is always appended to the end of the file."
+
+ At present, the single NuttX file pointer is positioned to the
+ end of the file for both reading and writing.
+ Status: Open
+ Priority: Medium. This kind of operation is probably not very common in
+ deeply embedded systems but is required by standards.
