* Bugs: |
| 15 |
* Commented out warnings of type mis-matches in check_and_copy_key |
| 16 |
* There is evidently a bug in append_keyval_to_primekeyval() in keystuff.c, |
| 17 |
* as the ingest_track module was generating a seg fault in |
| 18 |
* drms_setkey_string() with values of the PrimeKeyString like |
| 19 |
* 1987:000.0|22.5|-52.5|2002.03.30_00:44:30_TAI|1664|16.0|16.0|0.100000|0.000000|Postels|0.12500|0.00000|prog:mdi,level:lev1.5,series:fd_V_01h[80986-81014],sel:[53-36] |
| 20 |
* I was only able to work around this by changing the initial value of |
| 21 |
* buflen in append_keyval_to_primekeyval() from 128 to 256 |
| 22 |
* Many combinations of legitimate prefixes and unit strings for WCS time |
| 23 |
* descriptions are not yet supported |
| 24 |
* Consistency of floating-point key values in check_and_setkey_XXX is |
| 25 |
* only guaranteed to within the recommended format precision; this is |
| 26 |
* by design |
| 27 |
* check_and_setkey unimplemented for keys of type char and long long |
| 28 |
* |

* Revision History (all mods by Rick Bogart unless otherwise noted) |
| 740 |
* |
| 741 |
* 09.04.27 or earlier created file |
| 742 |
* 09.05.16 added functions for creating prime key string |
| 743 |
* 09.11.06 added WCS parsing function |
| 744 |
* 09.11.09 modified check_and_set_key_* to only require matching |
| 745 |
* to precision of keyword format for float, double, & time |
| 746 |
* 09.12.02 fixed two icc11 compiler warnings and one error |
| 747 |
* 10.01.07 added support in check_and_copy_key for keywords that |
| 748 |
* are dynamic links (in which case checking is irrelevant) |
| 749 |
* 10.02.03 relaxed check in check_and_copy_key (too much) |
| 750 |
* 10.04.24 added copy_prime_keys() |
| 751 |
* 10.06.11 added construct_stringlist() (orig in drms_rebin) |
