DataTypeGetInfo

Get information about a data type

SYNOPSIS

dip_Error dip_DataTypeGetInfo( dataType, info, whatInfo )

ARGUMENTS

Data typeNameDescription
dip_DataTypedataTypeThe data type to get information about
void *infoPointer to a variable to put the information in
dipf_DataTypeGetInfowhatInfoWhat information should be returned

FUNCTION

Get information about a data type. Depending on the whatInfo flag this routine will return information about the data type through the info parameter. A pointer must be passed to this routine which must point to a variable of the proper type to contain the information which will be returned. This pointer is passed as a void pointer through the info parameter. Below is a table of the flags that determine what information is returned, the type of the variable that is used to store the information in and a description of the information that is returned.

DIP_DT_INFO_C2Rdip_DataTypefor complex types returns the corresponding floating point type (i.e. dip_scomplex -> dip_sfloat) for other data types returns the data type itself

The following table shows which dip_DataTypeProperties flags are set for which data types:
