>From 1a1f8b9dbb68bf43c831e471ab4308d81a113ecd Mon Sep 17 00:00:00 2001 From: Jim Fehlig Date: Tue, 25 Aug 2009 15:54:18 -0600 Subject: [PATCH] Fix sexpr2string() to handle empty list. S-expression containing empty lists, e.g. (cpus (() () () ())), was not being handled properly in sexpr2string() serialization. Emit an empty list when encountering NIL sexpr kind. --- src/sexpr.c | 4 ++++ 1 files changed, 4 insertions(+), 0 deletions(-) diff --git a/src/sexpr.c b/src/sexpr.c index bc82d1f..81cb49f 100644 --- a/src/sexpr.c +++ b/src/sexpr.c @@ -255,6 +255,10 @@ sexpr2string(const struct sexpr * sexpr, char *buffer, size_t n_buffer) ret += tmp; break; case SEXPR_NIL: + tmp = snprintf(buffer + ret, n_buffer - ret, "()"); + if (tmp == 0) + goto error; + ret += tmp; break; default: goto error; -- 1.6.0.2
