! FORTRAN 90 Implementation: bufr_get_string_array
!
! Description: how to get an array of strings from a BUFR message.
program bufr_get_string_array
use eccodes
implicit none
integer :: ifile
integer :: iret,i,n
integer :: ibufr
integer :: strsize
integer, parameter :: max_strsize = 20
character(len=max_strsize) , dimension(:),allocatable :: stationOrSiteName
call codes_open_file(ifile,'../../data/bufr/pgps_110.bufr','r')
call codes_bufr_new_from_file(ifile,ibufr,iret)
! Unpack the data values
call codes_set(ibufr,'unpack',1)
! Get the width of the strings which is the same for all of them
call codes_get(ibufr,'stationOrSiteName->width',strsize)
! The width is given in bits
strsize=strsize/8
! max_strsize has to be set to a value >= to the size of the strings that we are getting
! back from the call to codes_get_string_array
if (strsize > max_strsize) then
print *,'stationOrSiteName array dimension is ',max_strsize,' and should be ',strsize
call exit(1)
end if
! Allocating the array of strings to be passed to codes_get_string_array is mandatory
call codes_get_size(ibufr,'stationOrSiteName',n)
allocate(stationOrSiteName(n))
! Passing an array of strings stationOrSiteName which must be allocated beforehand
call codes_get_string_array(ibufr,'stationOrSiteName',stationOrSiteName)
do i=1,n
write(*,'(A)')trim(stationOrSiteName(i))
end do
! Remember to deallocate
deallocate(stationOrSiteName)
! Release memory associated with bufr handle
! ibufr won't be accessible after this
call codes_release(ibufr)
! Close file
call codes_close_file(ifile)
end program bufr_get_string_array
