Function Documentation

mtapGetConnection()

int mtapGetConnection

(

int

port

)

Checks if a multitap is connected to an opened port.

Parameters

port	is the port to be checked.

Returns

1 if a multitap exists on the specified port; !1 if there isno multitap on the specified port.

Definition at line 87 of file libmtap.c.

mtapInit()

int mtapInit

(

void

mtapPortClose()

int mtapPortClose

(

int

port

)

Closes a port for the multitap.

Parameters

port	is a port that is to be closed (must have been previously opened by mtapPortOpen).

Returns

1 on success; !1 on failure.

Definition at line 77 of file libmtap.c.

mtapPortOpen()

int mtapPortOpen

(

int

port

)

Open a port for the multitap.

Parameters

port	specifies the port that is to be monitored as a multitap connection destination.

Returns

1 on success; !1 on failure.
