Understanding MprInfo Functions and Information Headers

The following functions require that the caller pass an information structure or header as one of the parameters.

Administration function	Configuration function
No administration function	MprConfigTransportCreate
MprAdminTransportSetInfo	MprConfigTransportSetInfo
MprAdminInterfaceTransportSetInfo	MprConfigInterfaceTransportSetInfo
MprAdminInterfaceTransportAdd	MprConfigInterfaceTransportAdd

 

Similarly, the following functions return information headers.

Administration function	Configuration function
MprAdminTransportGetInfo	MprConfigTransportGetInfo
MprAdminInterfaceTransportGetInfo	MprConfigInterfaceTransportGetInfo

 

For the transport functions, the information header contains global information for the transport. For the client (InterfaceTransport) functions, the header contains information specific to the client (for example, OSPF) being administered.

The information headers and their contents should be manipulated only by using the MprInfo functions. Developers should not attempt to manipulate the contents of the information headers directly.

The interface-only functions such as MprAdminInterfaceSetInfo do not require the use of MprInfo functions. The information that is passed and returned with these functions is always in the form of an MPR_INTERFACE structure.
