/* $ Detailed_Input */

/*     CK             is the name of a C-kernel. */

/*     IDS            is an initialized SPICELIB set data structure. */
/*                    IDS optionally may contain a set of ID codes on */
/*                    input; on output, the data already present in */
/*                    IDS will be combined with ID code set found for the */
/*                    file CK. */

/*                    If IDS contains no data on input, its size and */
/*                    cardinality still must be initialized. */

/* $ Detailed_Output */

/*     IDS            is a SPICELIB set data structure which contains */
/*                    the union of its contents upon input with the set */
/*                    of ID codes of each object for which pointing data */
/*                    are present in the indicated CK file. The elements */
/*                    of SPICELIB sets are unique; hence each ID code in */
/*                    IDS appears only once, even if the CK file */
/*                    contains multiple segments for that ID code. */

/*                    See the Examples section below for a complete */
/*                    example program showing how to retrieve the ID */
/*                    codes from IDS. */

/* $ Parameters */

/*     None. */

/* $ Exceptions */

/*     1)  If the input file has transfer format, the error */
/*         SPICE(INVALIDFORMAT) is signaled. */

/*     2)  If the input file is not a transfer file but has architecture */
/*         other than DAF, the error SPICE(BADARCHTYPE) is signaled. */

/*     3)  If the input file is a binary DAF file of type other than */
/*         CK, the error SPICE(BADFILETYPE) is signaled. */

/*     4)  If the CK file cannot be opened or read, the error will */
/*         be diagnosed by routines called by this routine. */

/*     5)  If the size of the output set argument IDS is insufficient to */
/*         contain the actual number of ID codes of objects covered by */
/*         the indicated CK file, the error will be diagnosed by */
/*         routines called by this routine. */

/* $ Files */

/*     This routine reads a C-kernel. */

/* $ Particulars */

/*     This routine provides an API via which applications can determine */
/*     the set of objects for which there are pointing data in a */
/*     specified CK file. */

/* $ Examples */

/*     1)  Display the interval-level coverage for each object in a */
/*         specified CK file. Use tolerance of zero ticks. Do not */
/*         request angular velocity. Express the results in the TDB time */
/*         system. */

/*         Find the set of objects in the file. Loop over the contents */
/*         of the ID code set:  find the coverage for each item in the */
/*         set and display the coverage. */
