as a sentinel value.
Return value¶
the numerical subtype of the binary value, or subtype_type(-1)
if no subtype is set
Exception safety¶
No-throw guarantee: this function never throws exceptions.
Complexity¶
Constant.
Version history¶
- Added in version 3.8.0
- Fixed return value to properly return
subtype_type(-1)
as documented in version 3.10.0.
