Pointer Error in c

[xyster]

Hello again,

got myself stuck again with my lack of time between coding c. Gotten myself lost with pointers this time i'm pretty sure.

Declaration in header file

extern DiskRequest proc_new_disk_request(int procnum, int sectornum, ReadOrWrite rw);

Where i'm calling it from and some code around it to make sense

algo_request(int procnum, ReadOrWrite rw, int sectornum)
{
    DiskRequest *new_request;
  
line 151:   new_request = proc_new_disk_request(procnum, sectornum, rw);

...
}

The function itself

DiskRequest proc_new_disk_request(int procnum, int sectornum, ReadOrWrite rw)
{
	DiskRequest *new_request;
	
    new_request = (DiskRequest *) checked_malloc(sizeof(DiskRequest));
    new_request->dr_procnum = procnum;
    new_request->dr_sectornum = sectornum;
    new_request->dr_rw = rw;
    new_request->dr_next = NULL;
    
    return *new_request;
}

The error the compiler is giving me:
disk.c:151: error: incompatible types in assignment

Change proc_new_disk_reques() to return a pointer and your program should compile

DiskRequest*  proc_new_disk_request(int procnum, int sectornum, ReadOrWrite rw)
{
	DiskRequest *new_request;
	
    new_request = (DiskRequest *) checked_malloc(sizeof(DiskRequest));
    new_request->dr_procnum = procnum;
    new_request->dr_sectornum = sectornum;
    new_request->dr_rw = rw;
    new_request->dr_next = NULL;
    
    return new_request;
}

Note that at some point in the program that pointer has to be free()'ed.
