Hello, If I trust the Siemens topic What should you watch out for when processing strings in scripts? No.1 - Description: No memory reserved form official documentation I understand that it is no need for memory allocation when getting a char tag value into a string like this: [code] char *valTag; valTag = GetTagChar("aCharTag"); [/code] Why there is no memory allocation for the Tag? I think that this operation should be like that: [code] char *valTag; valTag = SysMalloc(dim_of_aCharTag+1); valTag = GetTagChar("aCharTag"); [/code] How is correct: with or without SysMalloc()? Thanks! |
