  19     NAME
  20         strerror -- return the text for given error number
  21
  22     SYNOPSIS
  23         string = strerror(error);
  24
  25         char * strerror(int);
  26
  27     FUNCTION
  28         This function returns pointer to the (English) string describing the
  29         error code given as argument. The error strings are defined for the
  30         error codes defined in <sys/errno.h>.
  31
  32     NOTES
  33         The string pointed to by the return value should not be modified by
  34         the program, but may be overwritten by a subsequent call to this
  35         function.
  36
  37     BUGS
  38         The strerror() prototype should be
  39         const char *strerror(unsigned int);
  40         However, the SAS C includes define it differently.
