Examine or change connection attributes for asynchronous messaging
|Asynchronous messaging is an experimental feature; for information about the use of experimental software, see the Commercial Software License Agreement (CSLA) or Partner Software License Agreement (PSLA) in the Licensing area of our website, http://www.qnx.com/legal/licensing/.|
#include <sys/asyncmsg.h> int asyncmsg_connect_attr ( int coid, struct _asyncmsg_connection_attr *old_attr, const struct _asyncmsg_connection_attr *new_attr);
- The connection ID.
- NULL, or a pointer to a _asyncmsg_connection_attr structure where the function can store the current attributes for the connection.
- NULL, or a pointer to a _asyncmsg_connection_attr structure that specifies the attributes to set for the connection.
Use the -l asyncmsg option to qcc to link against this library.
You can use asyncmsg_connect_attr() to get or set the attributes to the connection used for asynchronous messaging:
- If old_attr isn't NULL, the function stores the current connection attributes in the structure that it points to.
- If new_attr isn't NULL, the function sets the connection attributes to the contents of the buffer it points to.
EOK, or -1 if an error occurred (errno is set).
- The connection specified by coid doesn't exist.
