+Check C stream handling functions:
+``fopen, fdopen, freopen, tmpfile, fclose, fread, fwrite, fgetc, fgets, fputc,
fputs, fprintf, fscanf, ungetc, getdelim, getline, fseek, fseeko, ftell,
ftello, fflush, rewind, fgetpos, fsetpos, clearerr, feof, ferror, fileno``.
+
+The checker maintains information about the C stream objects (``FILE *``) and
+can detect error conditions related to use of streams. The following conditions
+are detected:
+
+* The ``FILE *`` pointer passed to the function is NULL (the single exception
is
+ ``fflush`` where NULL is allowed).
+* Use of stream after close.
+* Opened stream is not closed.
+* Read from a stream after end-of-file. (This is not a fatal error but reported
+ by the checker. Stream remains in EOF state and the read operation fails.)
+* Use of stream when the file position is indeterminate after a previous failed
+ operation. Some functions (like ``ferror``, ``clearerr``, ``fseek``) are
+ allowed in this state.
+* Invalid 3rd ("``whence``") argument to ``fseek``.
+
+The stream operations are by this checker usually split into two cases, a
success
+and a failure case. However, in the case of write operations (like ``fwrite``,
+``fprintf`` and even ``fsetpos``) this behavior could produce a large amount of
+unwanted reports on projects that don't have error checks around the write
+operations, so by default the checker assumes that write operations always
succeed.
+This behavior can be controlled by the ``Pedantic`` flag: With
+``-analyzer-config unix.Stream:Pedantic=true`` the checker will model the
+cases where a write operation fails and report situations where this leads to
+erroneous behavior. (The default is ``Pedantic=false``, where write operations
+are assumed to succeed.)
