ets：i/1 ttyの2番目のオプションの意味

Question

gprocプロジェクトの内部構造を勉強しようとしています。 "ets：i/1"コマンドを使うとき、ttyは私に3つのオプションを与えます。 （p）数字の意味は？

(emacs@yus-iMac.local)35> ets:i(gproc). 
<1 > {{<0.77.0>,l}} 
<2 > {{<0.77.0>,{c,l,c1}},[{initial,3}]} 
<3 > {{<0.77.0>,{n,l,{dummy,1}}},[]} 
<4 > {{<0.77.0>,{p,l,prop}},[]} 
<5 > {{{c,l,c1},<0.77.0>},<0.77.0>,3} 
<6 > {{{n,l,{dummy,1}},n},<0.77.0>,undefined} 
<7 > {{{p,l,prop},<0.77.0>},<0.77.0>,undefined}

Answer 1

pNNNはレコード番号NNNを印刷します。例えば

：

(emacs@yus-iMac.local)35> ets:i(gproc). 
<1 > {{<0.77.0>,l}} 
<2 > {{<0.77.0>,{c,l,c1}},[{initial,3}]} 
<3 > {{<0.77.0>,{n,l,{dummy,1}}},[]} 
<4 > {{<0.77.0>,{p,l,prop}},[]} 
<5 > {{{c,l,c1},<0.77.0>},<0.77.0>,3} 
<6 > {{{n,l,{dummy,1}},n},<0.77.0>,undefined} 
<7 > {{{p,l,prop},<0.77.0>},<0.77.0>,undefined} 
EOT (q)uit (p)Digits (k)ill /Regexp -->p3 
{{<0.77.0>,{n,l,{dummy,1}}},[]}
