Detailed Description

Get a value of specified index from an array key.

Given an ID and key name as input a value corresponding to the given index is returned. The index is zero based i.e. the first element has zero index, the second element index one and so on. If the parameter index is an array all the values correspondig to the indexes list is returned. The ID references to a message loaded in memory.

In case of error, if the status parameter (optional) is not given, the program will exit with an error message.
Otherwise the error message can be gathered with codes_get_error_string.

Examples: grib_nearest.f90

Parameters

[in]	id	ID of the message loaded in memory
[in]	key	key name
[in]	index	index can be a scalar or array of integer(4)
[out]	value	value can be a scalar or array of integer(4),real(4),real(8)
[out]	status	CODES_SUCCESS if OK, integer value on error

Member Function/Subroutine Documentation

subroutine codes_get_real4_element	(	integer(kind=kindofint), intent(in)	msgid,
		character(len=*), intent(in)	key,
		integer(kind=kindofint), intent(in)	index,
		real(kind = kindoffloat), intent(out)	value,
		integer(kind=kindofint), intent(out), optional	status
	)

Get a real(4) value of specified index from an array key.

In case of error, if the status parameter (optional) is not given, the program will exit with an error message.
Otherwise the error message can be gathered with codes_get_error_string.

Parameters

msgid	id of the grib loaded in memory
key	key name
index	integer(4) index
value	real(4) value
status	CODES_SUCCESS if OK, integer value on error

subroutine codes_get_real4_elements	(	integer(kind=kindofint), intent(in)	msgid,
		character(len=*), intent(in)	key,
		integer(kind=kindofint), dimension(:), intent(in)	index,
		real(kind = kindoffloat), dimension(:), intent(out)	value,
		integer(kind=kindofint), intent(out), optional	status
	)

Get the real(4) values whose indexes are stored in the array "index" from an array key.

In case of error, if the status parameter (optional) is not given, the program will exit with an error message.
Otherwise the error message can be gathered with codes_get_error_string.

Parameters

msgid	id of the grib loaded in memory
key	key name
index	integer(4) array indexes
value	real(4) array value
status	CODES_SUCCESS if OK, integer value on error

subroutine codes_get_real8_element	(	integer(kind=kindofint), intent(in)	msgid,
		character(len=*), intent(in)	key,
		integer(kind=kindofint), intent(in)	index,
		real(kind = kindofdouble), intent(out)	value,
		integer(kind=kindofint), intent(out), optional	status
	)

Get a real(8) value of specified index from an array key.

In case of error, if the status parameter (optional) is not given, the program will exit with an error message.
Otherwise the error message can be gathered with codes_get_error_string.

Parameters

msgid	id of the grib loaded in memory
key	key name
index	integer(4) index
value	real(8) value
status	CODES_SUCCESS if OK, integer value on error

subroutine codes_get_real8_elements	(	integer(kind=kindofint), intent(in)	msgid,
		character(len=*), intent(in)	key,
		integer(kind=kindofint), dimension(:), intent(in)	index,
		real(kind = kindofdouble), dimension(:), intent(out)	value,
		integer(kind=kindofint), intent(out), optional	status
	)

Get the real(8) values whose indexes are stored in the array "index" from an array key.

In case of error, if the status parameter (optional) is not given, the program will exit with an error message.
Otherwise the error message can be gathered with codes_get_error_string.

Parameters

msgid	id of the grib loaded in memory
key	key name
