PtConnectionReply(), PtConnectionReplymx()

Reply to a message from a client

Synopsis:

int PtConnectionReply(
        PtConnectionServer_t *connection, 
        int len, 
        void const *buf );
int PtConnectionReplymx(
        PtConnectionServer_t *connection,
        int rparts,
        iov_t *riov );

Library:

ph

Description:

The server in a connection uses these functions to reply to a message sent by a client with a call to PtConnectionSend() or PtConnectionSendmx().

Under version 4 of the QNX RTOS, the iov_t type is a synonym for struct _mxfer_entry. The riov[0] entry is reserved for headers used internally by the library; the "real" reply buffer are defined by the contents of riov[1] through riov[rparts-1].

Returns:

0: Success.
-1: An error occurred; errno is set.

Classification:

Photon

Safety:
Interrupt handler	No
Signal handler	No
