+
+Compute the 32-bit CRC of @var{buf} which has length @var{len}.  The
+starting value is @var{init}; this may be used to compute the CRC of
+data split across multiple buffers by passing the return value of each
+call as the @var{init} parameter of the next.
+
+This is intended to match the CRC used by the @command{gdb} remote
+protocol for the @samp{qCRC} command.  In order to get the same
+results as gdb for a block of data, you must pass the first CRC
+parameter as @code{0xffffffff}.

+You must close @var{fp} using @code{fclose} yourself when you have
+finished writing data to the pipeline.
 
-@var{this_pname} is name of the calling program (i.e., @code{argv[0]}).
+The file descriptor underlying @var{fp} is marked not to be inherited
+by child processes.
 
-@var{temp_base} is the path name, sans suffix, of a temporary file to
-use if needed.  This is currently only needed for MS-DOS ports that
-don't use @code{go32} (do any still exist?).  Ports that don't need it
-can pass @code{NULL}.
+On systems that do not support pipes, this function returns
+@code{NULL}, and sets @code{errno} to @code{EINVAL}.  If you would
+like to write code that is portable to all systems the @code{pex}

-(@code{@var{flags} & PEXECUTE_SEARCH}) is non-zero if @env{PATH}

-correctly).  (@code{@var{flags} & PEXECUTE_FIRST}) is nonzero for the
-first process in chain.  (@code{@var{flags} & PEXECUTE_FIRST}) is
-nonzero for the last process in chain.  The first/last flags could be
-simplified to only mark the last of a chain of processes but that
-requires the caller to always mark the last one (and not give up
-early if some error occurs).  It's more robust to require the caller
-to mark both ends of the chain.
+There are two opportunities for deadlock using
+@code{pex_input_pipe}:
 
-The result is the pid on systems like Unix where we
-@code{fork}/@code{exec} and on systems like WIN32 and OS/2 where we
-use @code{spawn}.  It is up to the caller to wait for the child.
+@itemize @bullet
+@item
+Most systems' pipes can buffer only a fixed amount of data; a process
+that writes to a full pipe blocks.  Thus, if you write to @file{fp}
+before starting the first process, you run the risk of blocking when
+there is no child process yet to read the data and allow you to
+continue.  @code{pex_input_pipe} makes no promises about the
+size of the pipe's buffer, so if you need to write any data at all
+before starting the first process in the pipeline, consider using
+@code{pex_input_file} instead.
+
+@item
+Using @code{pex_input_pipe} and @code{pex_read_output} together
+may also cause deadlock.  If the output pipe fills up, so that each
+program in the pipeline is waiting for the next to read more data, and
+you fill the input pipe by writing more data to @var{fp}, then there
+is no way to make progress: the only process that could read data from
+the output pipe is you, but you are blocked on the input pipe.
 
-The result is the @code{WEXITSTATUS} on systems like MS-DOS where we
-@code{spawn} and wait for the child here.

+@var{executable} is the program to execute.  @var{argv} is the set of

+@var{outname} is used to set the name of the file to use for standard

+@enumerate

+@item

+Otherwise the code will use a file to hold standard

+a temporary file, and it will be removed when no longer needed, unless
+@code{PEX_SAVE_TEMPS} was set in the call to @code{pex_init}.
+
+There are two cases to consider when setting the name of the file to
+hold standard output.
+
+@enumerate
+@item
+@code{PEX_SUFFIX} is set in @var{flags}.  In this case
+@var{outname} may not be @code{NULL}.  If the @var{tempbase} parameter
+to @code{pex_init} was not @code{NULL}, then the output file name is
+the concatenation of @var{tempbase} and @var{outname}.  If
+@var{tempbase} was @code{NULL}, then the output file name is a random
+file name ending in @var{outname}.
+
+@item
+@code{PEX_SUFFIX} was not set in @var{flags}.  In this
+case, if @var{outname} is not @code{NULL}, it is used as the output
+file name.  If @var{outname} is @code{NULL}, and @var{tempbase} was
+not NULL, the output file name is randomly chosen using
+@var{tempbase}.  Otherwise the output file name is chosen completely
+at random.
+@end enumerate
+
+@var{errname} is the file name to use for standard error output.  If
+it is @code{NULL}, standard error is the same as the caller's.

+@var{tree_allocate_fn} and @var{node_allocate_fn} to use for allocating the

+@deftypefun int strverscmp (const char *@var{s1}, const char *@var{s2})
+The @code{strverscmp} function compares the string @var{s1} against
+@var{s2}, considering them as holding indices/version numbers.  Return
+value follows the same conventions as found in the @code{strverscmp}
+function.  In fact, if @var{s1} and @var{s2} contain no digits,
+@code{strverscmp} behaves like @code{strcmp}.
+
+Basically, we compare strings normally (character by character), until
+we find a digit in each string - then we enter a special comparison
+mode, where each sequence of digits is taken as a whole.  If we reach the
+end of these two parts without noticing a difference, we return to the
+standard comparison mode.  There are two types of numeric parts:
+"integral" and "fractional" (those  begin with a '0'). The types
+of the numeric parts affect the way we sort them:
+
+@itemize @bullet
+@item
+integral/integral: we compare values as you would expect.
+
+@item
+fractional/integral: the fractional part is less than the integral one.
+Again, no surprise.
+
+@item
+fractional/fractional: the things become a bit more complex.
+If the common prefix contains only leading zeroes, the longest part is less
+than the other one; else the comparison behaves normally.
