Function Documentation¶

int lupnt::cheby_segment(SpiceInt daf, SpiceDouble *dc, SpiceInt *ic, segment_t *s)¶

Read one Chebyshev-position-only SPK segment from an open DAF file into s, verifying its structure via cheby_verify.

Called by spk_extract for each Type-2 (Chebyshev position-only) segment found while scanning an SPK file.

Parameters:

daf – DAF file handle (from dafopr_c)
dc – Segment descriptor’s double-precision components (start/end epoch [s past J2000])
ic – Segment descriptor’s integer components (target/center/frame codes, representation type, data address range)
s – Output: populated segment descriptor (s->seg is heap-allocated)

Returns:

0 on success; 1 on error (with s->seg left as nullptr)
