The length of the "coords" array. Supply zero if "coords" is NULL.
coords
Pointer to an array holding "ncoords" AstKeyMap pointers (if "ncoords"
is zero, the supplied value is ignored). Each supplied KeyMapKeyMap
describes the contents of a single STC AstroCoords element, and
should have elements with keys given by constants AST__STCNAME,
AST__STCVALUE, AST__STCERROR, AST__STCRES, AST__STCSIZE,
AST__STCPIXSZ. Any of these elements may be omitted, but no other
elements should be included. If supplied, the AST__STCNAME element
should be a vector of character string pointers holding the "Name"
item for each axis in the coordinate system represented by
"region".
Any other supplied elements should be scalar elements, each holding
a pointer to a Region describing the associated item of ancillary
information (error, resolution, size, pixel size or value). These
Regions should describe a volume within the coordinate system
represented by "region".
options
Pointer to a null-terminated string containing an optional
comma-separated list of attribute assignments to be used for
initialising the new StcSearchLocation. The syntax used is identical to
that for the astSetastSet function and may include "printf" format
specifiers identified by "%" symbols in the normal way.
...
If the "options" string contains "%" format specifiers, then
an optional list of additional arguments may follow it in
order to supply values to be substituted for these
specifiers. The rules for supplying these are identical to
those for the astSet function (and for the C "printf"
function).
Returned Value:
astStcSearchLocation()
A pointer to the new StcSearchLocation.
Notes:
A deep copy is taken of the supplied Region. This means that
any subsequent changes made to the encapsulated Region using the
supplied pointer will have no effect on the Stc.
A null ObjectObject pointer (AST__NULL) will be returned if this
function is invoked with the AST error status set, or if it
should fail for any reason.
Status Handling
The protected interface to this function includes an extra
parameter at the end of the parameter list descirbed above. This
parameter is a pointer to the integer inherited status
variable: "int status".
