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