# PR_SetError

Sets error information within a thread context.

## Syntax

```{code}
#include <prerror.h>

void PR_SetError(PRErrorCode errorCode, PRInt32 oserr)
```

### Parameters

The function has these parameters:

`errorCode`

: The NSPR (platform-independent) translation of the error.

`oserr`

: The platform-specific error. If there is no appropriate OS error
  number, a zero may be supplied.

## Description

NSPR does not validate the value of the error number or OS error number
being specified. The runtime merely stores the value and returns it when
requested.
