Methods
Returns the name of the type.
Returns the identifier of the root type.
Returns the size of the type in bytes.
Returns the alignment of the type in bytes.
Returns the bit-mask of type attributes.
Returns the identifier of the enum value type.
Returns the type of array elements.
Returns the size of an array.
Returns the original type of the pointer.
Returns the field string names of a structure or union.
Returns the offset of the structure by the name of this field. In the case that the type is a union, then for each field of this type the offset will be equal to 0.
Returns the field type of a structure or union.
Returns the application binary interface (ABI) identifier with which you can call the function.
