a problem of"UF_MODL_ask_exps_of_feature"

[jiang]

i would like to get the expressions of the feature that got using "UF_UI_select_feature()",but it can not show the exptessions that i want to get,even the dialog of display the expressions is can not be shown,what is the reason,i need your help


char cue[] = "cue message";
int cnt=0, resp=0;
tag_t *feats;
char *feat_type;
FILE *fp=NULL;
char *string;
tag_t *exps;
int number_of_exps=0,i;
char buf[UF_UI_MAX_STRING_LEN+1];
char err_msg[MAX_LINE_SIZE+1];
char *expr_str;
char str[100];

fp=fopen("E:\\test.txt","w");
UF_CALL(UF_UI_select_feature(cue, NULL, &cnt, &feats, &resp));
UF_MODL_ask_feat_type(feats,&feat_type);
fprintf(fp,"\nfeature

Hello Jiang,


You can try this code to display the expressions of the model for which you are looking.

hello kishorev:


Thanks for your help,i have found the reason for the problem,


UF_CALL(UF_UI_select_feature(cue, NULL, &cnt, &feats, &resp));
if (cnt)
{
first = feats[0];
UF_free(feats);
}


it works.
