You are passing the wrong datatype to your function.  Your function is
expecting a filename, but when you call it you are trying to pass an
already-loaded bitmap. You might want to try:

show_centered_bmp("mydata.dat#Title_Main", 100);

Of course, you should probably change the function prototype from:

void show_centered_bmp(char filename[20],int y)

to 

void show_centered_bmp(char *filename,int y)

Does this help?
