Name

---

  MGH_N_BYTES

Purpose

---

  Return the total number of bytes in data element

Calling Sequence

---

      result = mgh_mgh_n_bytes(a)

Positional Parameters

---

  a (input, numeric or string, scalar or array)
    Data element whose size in bytes is to be returned.

Keyword Parameters

---

  LONG64 (input, switch)
    If set, return result as 64-bit integer. Default is long integer.

Return Value

---

  The total number of bytes in a is returned as an integer scalar.

Notes

---

  - For a string array, the number of bytes is computed after conversion
    with the BYTE() function, i.e. each element has the same length,
    equal to the maximum individual string length.

Modification History

---

  Written, based on N_BYTES in the IDL Astronomy Library. The
  motivation was that the return type was changed from a 32-bit
  integer to a 64-bit integer, breaking most of the code i used it
  in.
