Function Documentation

DLLEXTERNAL zForce* zForce_GetInstance

(

void

)

Get a zForce Instance.

Get a zForceInstance. This is a singleton so subsequent calls returns the same instance.

On error, errno is set.

• EZFORCENOTINITIALIZED - zForce not initialized.
• EMUTEXNOTINITIALIZED - Internal Error. Mutex not initialized.
• EMUTEXLOCKFAILED - Internal Error. Mutex Lock failed.

Returns

Pointer to zForce structure.

DLLEXTERNAL bool zForce_Initialize

(

OsAbstractionLayer *

osAbstractionLayer

)

Initializes zForce.

Initializes the zForce SDK. Must be called only once.

On error, errno is set.

• EALREADYINITIALIZED - zForce_Initialize has already been called.
• EMUTEXINITIALIZATIONFAILED - Failed initializing mutex.
• EZFORCEINITIALIZATIONFAILED - zForce Initialization failed.
• EZFORCENOTINITIALIZED - zForce not Initialized.

Parameters

osAbstractionLayer

Pointer to OsAbstractionLayer instance or NULL. Non-NULL members of the OsAbstractionLayer are copied so the supplied instance of OsAbstractionLayer can be freed by the caller after this call returns. If this argument is NULL, or any members of the supplied OsAbstractionLayer instance are NULL, default / OS specific functions are used instead.

Returns

True if successful, false if not, and errno set accordingly. See above for errno values.

DLLEXTERNAL void zForce_Uninitialize

(

void

)

Uninitializes zForce.

Unitializes zForce, freeing all allocated resources. No part of the zForce SDK should be used after this call.

On error, errno is set.

• EMUTEXDESTROYFAILED - Mutex Destroy failed.
• EBADMUTEX - Bad Mutex pointer.

Returns

No return value.
