There is NO way to clerify all unused functions in a program. You could call functions by their addresses and those addresses could be calculated in runtime. So you don't know... Something like this... ---<cut>--- int Funk1( void ) { printf("Funk1\n"); return(0); } int Funk2( void ) { printf("Funk2\n"); return(0); } main() { int event = -1; int (* ptrFunk)( void ); printf("Event 1 or 2: "); fgets( buffer, sizeof( buffer ), stdin ); event = atoi(buffer); switch(event) { case 1: ptrFunk = Funk2; break; case 2: ptrFunk = Funk1; break; default: printf("No function called\n"); } ptrFunk( ); } ---<cut>--- > nm --undefined-only *.o | cut -c12- | sort | uniq > would give you a list of all external symbols > > nm --defined-only *.o | cut -c12- | sort | uniq > would give you a list of all defined symbols > > now all enties in 2nd list, which are not in first list should be what you > are > looking for ('comm' should be able to do that). > > Stefan > > Dr. Michael J.
