Function Documentation

badval()

template<typename T , typename t , typename ... Args>

T throwcall::badval ( T  call, t  badvalue, const Args &...  args  )

inline

template function to wrap system calls that return a special bad value on failure

Parameters

[in]	call	the call, e.g. open(name,O_RDONLY)
[in]	badvalue	the special value returned on failure
[in]	args	get written to the what field of the exception

Returns

returns whatever the system call returns on success badvalue has a type different from T to allow nullptr badvalues, which would fail inference with more specific pointer return types
