The use of lstLib linked list function library on VxWorks

The lstLib on VxWorks defines the structure and functions of linked list operations. Flexible use will bring great convenience to programming.
The following is an example that shows the definition of LIST and NODE structures, as well as the create, add and next methods

#include<vxworks.h>
#include<lstLib.h>

typedef struct cmdData
{
    NODE    node;
    UINT32  cmd;
    UINT32  cmdIdx;
}cmdDATA;


LIST cmdList;
cmdDATA *pCmd=NULL;

void createCmdList(void)
{
    int i=0;
    lstInit(&cmdList);
    for(i=0;i<20;i++)
    {
        pCmd=(cmdDATA *)calloc(1,sizeof(cmdDATA));
        pCmd->cmd=i+1;
        pCmd->cmdIdx=i;
        lstAdd(&cmdList,(NODE *)pCmd);
    }
}


void dumpCmdList(void)
{
    int count=0;
    cmdDATA *pCmd=NULL;
    for(pCmd=(cmdDATA *)lstFirst(&cmdList);
            pCmd!=NULL;
            pCmd=lstNext((NODE *)pCmd))
    {
        count++;
        printf("cmd=0x%4x,cmdId=0x%04x\n",pCmd->cmd,pCmd->cmdIdx);
    }
}
