Probably you expected ERR to be a metavariable, but it's not. Actually, fully capitalizing your metavariables is not a good idea. Coccinelle expects that fully capitalized things are constants, as in #define ERR -1, and so when they appear at random places, it doesn't comment about that. If it had been in lowercase and used as the argument of a return (or as a function argument, right-hand side of an assignment, etc), Coccinelle would have printed a warning wondering if you expected it to be a metavariable. If ERR is declared as an expression metavariable, then lots of returns are replaced. julia _______________________________________________ Cocci mailing list Cocci@systeme.lip6.fr https://systeme.lip6.fr/mailman/listinfo/cocci
