msgcount - Number of messages in read-enabled channel queue

Syntax

msgcount(rx,'channel')

Description

msgcount(rx,'channel') returns the number of unread messages in the read-enabled queue specified by channel for the RTDX™ interface rx. You cannot use msgcount on channels configured for write access.

Examples

If you have created and loaded a program to the target processor, you can write data to the target, then use msgcount to determine the number of messages in the read queue.

1. Create and load a program to the target.

2. Write data to the target from MATLAB^® software.

   indata=1:100;
   writemsg(cc.rtdx,'ichannel', int32(indata));
   

3. Use msgcount to determine the number of messages available in the queue.

   num_of_msgs = msgcount(cc.rtdx,'ichannel')
