subroutine grib_api::grib_check ( integer,intent(in)  status,
character(len=*),intent(in)  caller,
character(len=*),intent(in)  string 
)

Check the status returned by a subroutine.

In case of error it stops the program, returns the error code to the shell and prints the error message.

Parameters:
status the status to be checked
caller name of the caller soubroutine
string a string variable from the caller routine (e.g. key,filename)

subroutine grib_api::grib_clone ( integer(kind=kindOfInt),intent(in)  gribid_src,
integer(kind=kindOfInt),intent(out)  gribid_dest,

)

Create a copy of a message.

Create a copy of a given message (gribid_src) giving a new
message in memory (gribid_dest) exactly identical to the original one.

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 grib_get_error_string.

)

Close a file.

If the fileid does not refer to an opened file an error code is returned in status.

Examples: get.f90

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

Parameters:
iterid keys iterator id created with grib_keys_iterator_new
name key name to be retrieved
status GRIB_SUCCESS if OK, integer value on error

subroutine grib_api::grib_keys_iterator_new ( integer(kind=kindOfInt),intent(in)  gribid,
integer(kind=kindOfInt),intent(out)  iterid,
character(LEN=*),intent(in)  namespace,
integer(kind=kindOfInt),intent(out),optional  status 
)

Create a new iterator on the keys.

The keys iterator can be navigated to give all the key names which can then be used to get or set the key values with grib_get or grib_set. The set of keys returned can be controlled with the input variable namespace or using the functions grib_skip_read_only, grib_skip_duplicates, grib_skip_coded,grib_skip_computed. If namespace is a non empty string only the keys belonging to that namespace are returned. Available namespaces are "ls" (to get the same default keys as the grib_ls and "mars" to get the keys used by mars.

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 grib_get_error_string.
