MessageReaderSettings

Settings that affect the way messages are read from a connected socket

Used as a member in struct TcpMsgSessionSettings.

struct MessageReaderSettings
{
    ssize_t normalCommitBufferSize;
    ssize_t maxMsgSize;
    ssize_t maxRecvSize;
};

---

ssize_t normalCommitBufferSize

The initial size of the read buffer

Default value : 16384 (16KB)

---

ssize_t maxMsgSize

The upper bound on the size of the body of an individual message (i.e. not including the 4 byte header giving the message size). Therefore it also represents the upper bound on the size of the receive buffer in memory. If the size of the body of a message exceeds this value then a fatal SC_ReadInvalidMessageSize error is raised on the connection. Making this value extremely large could make the machine vulnerable to running out of memory.

Default value : 67108864 (64 MB)

---

ssize_t maxRecvSize

The upper bound on the size of the receive buffer provided in the receive socket calls.

Default value : 262144 (256kB)
