HELP!! compile error C141

there are compile errors in the following
two function declaration.

void CAN_SETTXBID(unsigned char
node,unsigned char type);

int CAN_SETFILTER(unsigned char node);

they both have the following compile error:

error C141: syntax error near '0'

but there are no '0' in these two function declaration,so i can't figure out where
the '0' come from,and how should i correct
these codes?
