Detailed Description

Defines internal basic interpolation definitions.

This header defines internal constants and macros used throughout the interpolation module of YAC. It includes definitions for handling fractional masks and provides utility macros to check the state of fractional mask values.

Macro Definition Documentation

YAC_FRAC_MASK_VALUE_IS_SET

#define YAC_FRAC_MASK_VALUE_IS_SET

(

value

)

(!isnormal(value) || ((value) != YAC_FRAC_MASK_UNDEF))

Test whether a fractional mask value is explicitly set.

Evaluates to nonzero, if the value is either not a normal number (e.g. NaN/Inf) or differs from YAC_FRAC_MASK_UNDEF.

Definition at line 29 of file interpolation_internal.h.

YAC_FRAC_MASK_VALUE_IS_VALID

#define YAC_FRAC_MASK_VALUE_IS_VALID

(

value

)

Value:

  (!isnormal(value) || \
   (((value) != YAC_FRAC_MASK_UNDEF) && ((value) != YAC_FRAC_MASK_NO_VALUE)))

Test whether a fractional mask value is valid.

Evaluates to nonzero if the value is either not a normal number, or is different from both YAC_FRAC_MASK_UNDEF and YAC_FRAC_MASK_NO_VALUE.

Function Documentation

yac_interpolation_get_collection_selection()

struct yac_collection_selection const * yac_interpolation_get_collection_selection

(

struct yac_interpolation const *

interp

)

Return the collection selection associated with an interpolation.

The returned pointer is owned by the interpolation object; the caller must not free it. If interp is NULL the function returns NULL.

Parameters

[in]

interp

Pointer to interpolation object (may be NULL).

Returns

Pointer to the collection selection (const), or NULL.
