From: David Schleef Date: Fri, 8 Feb 2008 03:44:12 +0000 (+0000) Subject: gst/multifile/: Use g_file_[sg]et_contents() instead of using stdio functions. X-Git-Tag: 1.19.3~509^2~11468 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=da83e9f450e0f036dd204f2a1a84a950676113be;p=platform%2Fupstream%2Fgstreamer.git gst/multifile/: Use g_file_[sg]et_contents() instead of using stdio functions. Original commit message from CVS: * gst/multifile/gstmultifilesink.c: * gst/multifile/gstmultifilesrc.c: Use g_file_[sg]et_contents() instead of using stdio functions. Should be less error prone. * tests/check/elements/multifile.c: Create a temporary directory using standard functions instead of creating a directory in the current dir. --- diff --git a/gst/multifile/gstmultifilesink.c b/gst/multifile/gstmultifilesink.c index dd7e1f4..583b989 100644 --- a/gst/multifile/gstmultifilesink.c +++ b/gst/multifile/gstmultifilesink.c @@ -49,7 +49,7 @@ GST_DEBUG_CATEGORY_STATIC (gst_multi_file_sink_debug);
