The process needs to read() data off the pipe in order to clear it otherwise it blocks and stays in the pipe. Invoke read() after exec'ing program B in the child process.

SPELL(1)						      General Commands Manual							  SPELL(1)

NAME

       spell - GNU spell, a Unix spell emulator

SYNOPSIS

       spell [options] files ...

DESCRIPTION

       This  manual  page documents briefly the spell command. This manual page was written for the Debian GNU/Linux distribution (but may be used
       by others), because the original program does not have a manual page. Instead, it has documentation in the GNU Info format; see below.

       spell is a program that emulates the traditional Unix spell command by calling the Ispell utility.

       It is a spell checking program which prints each misspelled word on a line of its own.

OPTIONS

       The programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options are  included
       below. For a complete description, see the Info files.

       -I, --ispell-version
	      Print Ispell's version.

       -V, --version
	      Print the version number.

       -b, --british
	      Use the British dictionary.

       -d, --dictionary=FILE
	      Use FILE to look up words.

       -h, --help
	      Print a summary of the options.

       -i, --ispell=PROGRAM
	      Calls PROGRAM as Ispell.

       -D, --ispell-dictionary=DICTIONARY
	      Use the named DICTIONARY to look up words.

       -l, --all-chains
	      Ignored; for compatibility.

       -n, --number
	      Print line numbers before lines.

       -o, --print-file-name
	      Print file names before lines.

       -s, --stop-list=FILE
	      Ignored; for compatibility.

       -v, --verbose
	      Print words not literally found.

       -x, --print-stems
	      Ignored; for compatibility.

SEE ALSO

       The programs are documented fully by GNU Spell, a clone of Unix `spell', available via the Info system.
