Explain BSD vs glibc "a+" difference
Where is the initial read position for an "a+" stream?
Where is the initial read position for an "a+" stream?
POSIX leaves this unspecified. Most BSD man pages are silent, and
MacOS has the ambiguous "The stream is positioned at the end of
the file", not differentiating between reads and writes other than
to say that fseek(3) does not affect writes. glibc's documentation
explicitly specifies that the initial read position is the
beginning of the file.

My new wording is based on the BSD implementations, so you may
prefer to replace the non-glibc section with "unspecified", or
indeed remove all claims about the initial read position.
