getlocal()

subroutine getlocal	(	character(len = 1), dimension(lcgrib), intent(in)	cgrib,
		integer, intent(in)	lcgrib,
		integer, intent(in)	localnum,
		character(len = 1), dimension(*), intent(out)	csec2,
		integer, intent(out)	lcsec2,
		integer, intent(out)	ierr
	)

This subroutine returns the contents of Section 2 from a GRIB2 message.

Since there can be multiple occurrences of Section 2 within a GRIB message, the calling routine indicates which occurrence is being requested with the localnum argument.

Note

Note that subroutine gb_info() can be used to first determine how many Local Use sections exist in a given GRIB message.

Parameters

[in]	cgrib	Character array that contains the GRIB2 message.
[in]	lcgrib	Length (in bytes) of GRIB message array cgrib.
[in]	localnum	The nth occurrence of Section 2 requested.
[out]	csec2	Character array containing information read from Section 2. The dimension of this array can be obtained in advance from argument maxlocal, which is returned from subroutine gb_info().
[out]	lcsec2	Number of bytes of character array csec2 read from Section 2.
[out]	ierr	Error return code. 0 no error. 1 Beginning characters "GRIB" not found. 2 GRIB message is not Edition 2. 3 The data field request number was not positive. 4 End string "7777" found, but not where expected. 5 End string "7777" not found at end of message. 6 GRIB message did not contain the requested number of data fields.
