void removc_c ( ConstSpiceChar * item,
SpiceCell * set )
Remove an item from a character set.
VARIABLE I/O DESCRIPTION
-------- --- --------------------------------------------------
item I Item to be removed.
set I/O Removal set.
item is an item which is to be removed from the specified
set. item may or may not already be an element of the
set. Trailing blanks in item are not significant.
set is a CSPICE set. set must be declared as a character
On input, set may or may not contain the input item
as an element.
set on output contains the difference of the input set and
the input item. If the item is not an element of the
set, the set is not changed.
1) If the input set argument is a SpiceCell of type other than
character, the error SPICE(TYPEMISMATCH) is signaled.
2) If the input set argument does not qualify as a CSPICE set,
the error SPICE(NOTASET) will be signaled. CSPICE sets have
their data elements sorted in increasing order and contain
no duplicate data elements.
3) If the input string pointer is null, the error SPICE(NULLPOINTER)
1) In the following example, the element "PLUTO" is removed from
the character set planets and inserted into the character set
Declare the sets with string length NAMLEN and with maximum
number of elements MAXSIZ.
SPICECHAR_CELL ( planets, MAXSIZ, NAMLEN );
SPICECHAR_CELL ( asteroids, MAXSIZ, NAMLEN );
removc_c ( "PLUTO", &planets );
insrtc_c ( "PLUTO", &asteroids );
If "PLUTO" is not an element of planets, then the contents of
planets are not changed. Similarly, if "PLUTO" is already an
element of asteroids, the contents of asteroids remain unchanged.
1) String comparisons performed by this routine are Fortran-style:
trailing blanks in the input set or key value are ignored.
This gives consistent behavior with CSPICE code generated by
the f2c translator, as well as with the Fortran SPICE Toolkit.
Note that this behavior is not identical to that of the ANSI
C library functions strcmp and strncmp.
