APR, Shared Memory and extern process

[ricardo13]

Hi,

I'm writing a apache's module that comunicate with a extern process.

My extern process is built in C:

        char*  shm_address;
        int    shmid;
        key_t  shmkey;

        shmkey = 5678;
        shmid = shmget(shmkey, SIZEOFSHMSEG, 0666);
        if (shmid == -1)
                printf("main: shmget() failed\n");
      
        shm_address = shmat(shmid, NULL, 0);
        if ( shm_address==NULL )
                printf("main: shmat() failed\n");        

        while(1) {
                if(strcmp(shm_address, ":") == 0) {
                        strcpy(shm_address, data);
                        break;
                }
        }

        int rc = shmdt(shm_address);
        if (rc==-1)
                printf("main: shmdt() failed\n");


Now I want to write a module that take (or get) the information in this
segment.
Can someone help me ??

Thank You

Ricardo
