Error on strtok_r

[william.basser]

I have a software module that parses incoming commands and tokenizes the command buffer into arguments. I get the following error when it attempts to parse the buffer
I (184388) CTLASCCMD:: Event Received 0

Any ideas?

Can't pass NULL to strtok_r().

Instead of

Code: Select all

PPC8            pccTemp = NULL;
...
    // get the command
    pcArg = strtok_r( ptCmdLinCtl->pcBuffer, szDelims, pccTemp );

you want

Code: Select all

PC8 pcTemp = NULL;
...
    // get the command
    pcArg = strtok_r( ptCmdLinCtl->pcBuffer, szDelims, &pcTemp );
