passing values from map to list

hi happy new year,

here "UF_STRING_t * sectionEditData" is pointer to the string structure of a single string to add or replace.

but for some reason i am not getting output of"UF_MODL_replace_feat_strings" function"

can anyone help me?

Code:

void defGeometry::ReplaceSpline(std::vector<struct geometricSection>sections)
{
	int j=1;
	tag_t PartTag=NULL_TAG;
	tag_t feat_tag=NULL_TAG;
	char feat_name[]="THROUGH";
	UF_STRING_t * sectionEditData=NULL;
	sectionEditData= (UF_STRING_t *) malloc (sizeof(UF_STRING_t)*ActionSide.NumberOfSections);
	PartTag=UF_PART_ask_display_part();
	UF_CALL(UF_OBJ_cycle_by_name_and_type (PartTag, feat_name, UF_feature_type, FALSE, &feat_tag));
if(!feat_tag)
	{
		sysLogPrint("Failed to create spline !");
}
else
{
	sysLogPrint("s.t=&#37;d",feat_tag);
	
}
for(int i=0;i<ActionSide.NumberOfSections;i++ )
{
	int k=0;
	UF_MODL_init_string_list(&sectionEditData[i]);
	UF_MODL_create_string_list(1, 4, &sectionEditData[i]);
	sectionEditData[i].string[0]=4;
	sectionEditData[i].dir[0]=UF_MODL_CURVE_START_FROM_BEGIN;

	for( map<int,tag_t>::iterator iter = sections[i].section_tags.begin();iter != sections[i].section_tags.end(); iter++)
	{
		sectionEditData[i].id[k]=(*iter).second;
		k++;	
	
	if( j<=3)
	{
		if(!UF_CALL(UF_MODL_replace_feat_strings (feat_tag, UF_MODL_STRING_REPLACE, &sectionEditData[i], 1, j++)))
		{
			sysLogPrint("spline replaced j<=3");
		}
		else
		{
			sysLogPrint("spline not replacedj<=3");
		}		
	}
	else
	{
		UF_CALL(UF_MODL_replace_feat_strings (feat_tag, UF_MODL_STRING_ADD, &sectionEditData[i], 1, (j++)-1));
	}
	
	
	UF_MODL_update ();
	}
}

What's the error? Where's the error? Is sectionEditData[i].id[k] a tag_t?
