What does...
test.c:11: warning: passing arg 5 of `bsearch' from incompatible pointer type
...mean?  Here's the code (which, incidentally, raises no problems
with ULTRIX's cc)...

#include <stdlib.h>
#include <string.h>

int charcompare( char, char );

main() {
  char str1[10], *str2;
  strcpy( str1, "abcdefghi" );

  str2 = bsearch( (char *)'e', str1, 9, 1, charcompare );
}
/*---------------------------------*/

int charcompare( char ch1, char ch2 ) {
   return ch1 - ch2;
}
