Function Documentation

unsigned char CheckForKBCharacter

(

void

)

Checks for one single keyboard stroke.

The function returns immediately.

Returns:

• Value of the pressed key
• 255 if no key was pressed

See also:

WaitForKBCharacter()

Definition at line 205 of file QNXAbstraction.cpp.

int DisableSingleCharacterInput

(

void

)

---

int EnableSingleCharacterInput

(

void

)

float GetSystemTimeInSeconds

(

const bool &

Reset

)

Returns a time value in seconds.

Operating system independent function to return the value of the system time in seconds.

Parameters:

Reset

If this flag is set, the value of this system time will be set to zero.

Returns:

The value of the system time in seconds.

Definition at line 230 of file QNXAbstraction.cpp.

unsigned char WaitForKBCharacter

(

bool *

Abort

)

Waits for one single keyboard stroke.

The function returns after the stroke or if Abort becomes set. If Abort is set at the call of the function, the function only checks once, if a key has been pressed.

Parameters:

Abort

Pointer to a boolean values, which lets the function terminate

Returns:

• Value of the pressed key
• 255 if no key was pressed
