This list is used by the STREAMS socket call to open the appropriate transport provider. The library also provides facilities to delete the protocol entry from the list.<p>The <b><i>strmSockLibInit</i>( )</b> routine initializes the table of function pointers with STREAMS sockets calls. This ensures that the socket calls areconfigured to use either BSD sockets or WindNet STREAMS sockets.<p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./strmSockLib.html#top">strmSockLib</a></b>, <i>WindNet STREAMS Optional Component Supplement </i><hr><a name="strmSockProtoAdd"></a><p align=right><a href="rtnIndex.html"><i>Libraries : Routines</i></a></p></blockquote><h1><i>strmSockProtoAdd</i>( )</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote> <p><strong><i>strmSockProtoAdd</i>( )</strong> - add a new transport-protocol entry to STREAMS sockets (STREAMS Option)</p></blockquote><h4>SYNOPSIS</h4><blockquote><p><pre>STATUS strmSockProtoAdd ( int family, /* address family of added protocol */ int type, /* socket type of added protocol */ char * devName /* transport provider device name */ )</pre></blockquote><h4>DESCRIPTION</h4><blockquote><p>This routine enables transport independence for the STREAMSsocket library by adding transport-provider entries to the table. It must be called for all transport providers that use the STREAMS socket interface. Thisroutine must be executed before applications call <b><i><a href="./sockLib.html#socket">socket</a></i>( )</b>. The table consists of three fields: the address family (<b>AF_INET</b>, <b>AF_CCITT</b>), the socket type (<b>SOCK_STREAM</b>, <b>SOCK_RAW</b>), and the transport-provider device name. The socket library decides on an appropriate transport provider based on the address-family and socket-type parameters passed to the <b><i><a href="./sockLib.html#socket">socket</a></i>( )</b>.<p></blockquote><h4>WARNING</h4><blockquote><p>Two different transport providers having the same address family andsocket type cannot be added to the table.<p></blockquote><h4>EXAMPLE</h4><blockquote><p><p><pre>strmSockProtoAdd (AF_INET, SOCK_DGRAM, "/dev/udp")</pre></blockquote><h4>RETURNS</h4><blockquote><p>OK, or ERROR if the transport-provider entry cannot be made.<p></blockquote><h4>ERRNO</h4><blockquote><p>S_strmLib_DUPLICATE_PROVIDER</blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./strmSockLib.html#top">strmSockLib</a></b><hr><a name="strmSockProtoDelete"></a><p align=right><a href="rtnIndex.html"><i>Libraries : Routines</i></a></p></blockquote><h1><i>strmSockProtoDelete</i>( )</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote> <p><strong><i>strmSockProtoDelete</i>( )</strong> - remove a protocol entry from the table (STREAMS Option)</p></blockquote><h4>SYNOPSIS</h4><blockquote><p><pre>STATUS strmSockProtoDelete ( int family, /* address family */ int type /* socket type */ )</pre></blockquote><h4>DESCRIPTION</h4><blockquote><p>This routine removes a protocol entry from the table.
