How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you

realloc“safely,” you can useMyType *NewPointer = realloc(OldPointer, NewSize); if (!NewPointer) { Do error handling here, such as writing an error message to stderr and terminating the program. } OldPointer = NewPointer;. Although, if your error handling consists only of reporting an error and terminating the program, it does not matter if you usedata = realloc(data, dataIndex + 1);in a typical system, as the operating system will reclaim all memory when your program terminates. (It is actually wasteful to “clean up” things that are purely internal to the program.)
