# explain\_iconv\_close\_or\_die(3)

deallocate conversion descriptor and report errors

## NAME

explain\_iconv\_close\_or\_die - deallocate conversion descriptor and report errors

## SYNOPSIS

\#include \<libexplain/iconv\_close.h\>

void explain\_iconv\_close\_or\_die(iconv\_t cd);\
 int explain\_iconv\_close\_on\_error(iconv\_t cd);

## DESCRIPTION

The **explain\_iconv\_close\_or\_die** function is used to call the [*iconv\_close*(3)](/iconv_close/3.md) system call. On failure an explanation will be printed to *stderr*, obtained from the [*explain\_iconv\_close*(3)](/explain_iconv_close/3.md) function, and then the process terminates by calling `exit(EXIT_FAILURE)`.

The **explain\_iconv\_close\_on\_error** function is used to call the [*iconv\_close*(3)](/iconv_close/3.md) system call. On failure an explanation will be printed to *stderr*, obtained from the [*explain\_iconv\_close*(3)](/explain_iconv_close/3.md) function, but still returns to the caller.

- *cd*

  The cd, exactly as to be passed to the [*iconv\_close*(3)](/iconv_close/3.md) system call.

## RETURN VALUE

The **explain\_iconv\_close\_or\_die** function only returns on success, see [*iconv\_close*(3)](/iconv_close/3.md) for more information. On failure, prints an explanation and exits, it does not return.

The **explain\_iconv\_close\_on\_error** function always returns the value return by the wrapped [*iconv\_close*(3)](/iconv_close/3.md) system call.

## EXAMPLE

The **explain\_iconv\_close\_or\_die** function is intended to be used in a fashion similar to the following example:

```
explain_iconv_close_or_die(cd);
```

## SEE ALSO

- [*iconv\_close*(3)](/iconv_close/3.md)

  deallocate descriptor for character set conversion

- [*explain\_iconv\_close*(3)](/explain_iconv_close/3.md)

  explain [*iconv\_close*(3)](/iconv_close/3.md) errors

- [*exit*(2)](/exit/2.md)

  terminate the calling process
