Procedure
ktotal_c ( Kernel Totals )
void ktotal_c ( ConstSpiceChar * kind,
SpiceInt * count )
AbstractReturn the number of kernels of a specified type that are currently loaded via the furnsh_c interface. Required_ReadingKERNEL KeywordsKERNEL Brief_I/OVARIABLE I/O DESCRIPTION -------- --- -------------------------------------------------- kind I A list of kinds of kernels to count. count O The number of kernels of type `kind'. Detailed_Input
kind is a list of types of kernels to count when computing
loaded kernels. `kind' should consist of a list of words of
kernels to examine. Recognized types are
SPK --- All SPK files are counted in the total.
CK --- All CK files are counted in the total.
PCK --- All binary PCK files are counted in the
total.
DSK --- All DSK files are counted in the total.
EK --- All EK files are counted in the total.
TEXT --- All text kernels that are not meta-text
kernels are included in the total.
META --- All meta-text kernels are counted in the
total.
ALL --- Every type of kernel is counted in the
total.
`kind' is case insensitive. If a word appears in `kind'
that is not one of those listed above, it is ignored.
When `kind' consists of multiple words, the words must
be separated by blanks. Examples of valid lists are the
strings
"SPK CK TEXT"
"SPK CK text"
"PCK DSK"
"CK"
"ALL"
See the -Examples section for illustrations of the
use of `kind'.
Detailed_Outputcount is the number of kernels loaded through furnsh_c that belong to the list specified by `kind'. ParametersNone. Exceptions
1) If a word on the list specified by `kind' is not recognized,
it is ignored.
2) If `kind' is blank, or none of the words in `kind' is on the
list specified above, `count' will be returned as zero.
3) If the `kind' input string pointer is null, the error
SPICE(NULLPOINTER) is signaled.
4) If the `kind' input string has zero length, the error
SPICE(EMPTYSTRING) is signaled.
FilesNone. Particularsktotal_c allows you to easily determine the number of kernels loaded via the interface furnsh_c that are of a type of interest. Examples
The numerical results shown for this example may differ across
platforms. The results depend on the SPICE kernels used as
input, the compiler and supporting libraries, and the machine
specific arithmetic implementation.
1) Load a meta-kernel with a PCK, an LSK and an SPK, and
separately, a text kernel and a binary PCK. Show the
total number of kernels and meta-kernels loaded. Determine the
number of text kernels loaded, and the number of binary
kernels.
Unload all kernels and clear the kernel pool using
kclear_c, and check that no kernels are loaded.
Use the meta-kernel shown below to load the required SPICE
kernels.
KPL/MK
File name: ktotal_ex1.tm
This meta-kernel is intended to support operation of SPICE
example programs. The kernels shown here should not be
assumed to contain adequate or correct versions of data
required by SPICE-based user applications.
In order for an application to use this meta-kernel, the
kernels referenced here must be present in the user's
current working directory.
The names and contents of the kernels referenced
by this meta-kernel are as follows:
File name Contents
--------- --------
de421.bsp Planetary ephemeris
pck00008.tpc Planet orientation and
radii
naif0009.tls Leapseconds

KERNELS_TO_LOAD = ( 'de421.bsp',
'pck00008.tpc',
'naif0009.tls' )

End of meta-kernel
Use the PCK kernel below as the binary PCK required for the
example.
earth_latest_high_prec.bpc
Use the FK kernel below as the text kernel required for the
example.
RSSD0002.TF
Example code begins here.
/.
Program ktotal_ex1
./
#include <stdio.h>
#include "SpiceUsr.h"
SpiceInt count;
int main()
{
/.
Load several kernel files.
./
furnsh_c( "ktotal_ex1.tm" );
furnsh_c( "RSSD0002.TF" );
furnsh_c( "earth_latest_high_prec.bpc" );
/.
Count the number of loaded kernel files.
./
ktotal_c ( "ALL", &count );
printf ( "The total number of kernels after "
"final furnsh_c: %d\n", count );
/.
Count the number of meta-kernels.
./
ktotal_c ( "META", &count );
printf ( "The total number of meta-kernels "
" : %d\n", count );
/.
Count the number of text kernels.
./
ktotal_c ( "TEXT", &count );
printf ( "The total number of text kernels "
" : %d\n", count );
/.
Count the number of binary kernels. These kernels
are of type CK, DSK, EK, PCK or SPK.
./
ktotal_c ( "CK DSK EK PCK SPK", &count );
printf ( "The total number of binary kernels"
" : %d\n", count );
/.
Clear the KEEPER system, retrieve the number of loaded
after the clear.
./
kclear_c ( );
ktotal_c ( "ALL", &count );
printf ( "The total number of kernels after "
"kclear_c : %d\n", count );
}
When this program was executed on a Mac/Intel/cc/64-bit
platform, the output was:
The total number of kernels after final furnsh_c: 6
The total number of meta-kernels : 1
The total number of text kernels : 3
The total number of binary kernels : 2
The total number of kernels after kclear_c : 0
