* NAME
* strerror - string for error number
*
* SYNOPSIS
* char *strerror(int errnum);
*
* DESCRIPTION
* The strerror function maps the error number in errnum to an error
* message string.
*
* RETURNS
* The strerror function returns a pointer to the string, the contents of
* which are implementation-defined. The array pointed to shall not be
* modified by the program, but may be overwritten by a subsequent call to
* the strerror function.
*
* CAVEAT
* Unknown errors will be rendered in the form "Error %d", where %d will
* be replaced by a decimal representation of the error number.
