LinuxQuestions.org - index of an element in the array ?

Hello,

is it (and how is it) possible in C to get the index of an element in the array ? for example, with the 'bsearch' function.

Thanks

well, i think the solution is quite simple:

Code:

int get_index( type element, type* array, int arraysize) {

  type *buffer;

  buffer = bsearch( &element, array, arraysize, sizeof( type), compare);

  if( buffer == NULL)

    return -1;

  return ((long) buffer - (long) array) / sizeof( type);

}



int compare( void* first, void* second) {

  if( (type*) first == (type*) second)

    return 0; 

  ...

}
