# TSMimeHdrCopy(3ts)

TSMimeHdrCopy API function

## NAME

TSMimeHdrCopy - TSMimeHdrCopy API function

## SYNOPSIS

```
#include <ts/ts.h>
```

- ***TSReturnCode* TSMimeHdrCopy(*TSMBuffer* dest\_bufp, *TSMLoc* dest\_offset, *TSMBuffer* src\_bufp, *TSMLoc* src\_offset)**

  ## DESCRIPTION

Copies the contents of the MIME header located at *src\_loc* within *src\_bufp* to the MIME header located at *dest\_loc* within *dest\_bufp*.

*TSMimeHdrCopy()* works correctly even if *src\_bufp* and *dest\_bufp* point to different marshal buffers.

**IMPORTANT:**

You must create the destination MIME header before copying into it, using *TSMimeHdrCreate()*.
