A helper algorithm for remove_if() . Erases all elements that satisfy pred from the container c . Unlike remove_if() , the size of the container decreases by the number of elements that are erased.

Declaration


  #include <ospace/helper/helpalgo.h>

template< class Container, class Predicate >
void os_erase_if( Container& c, Predicate pred )

Example <ospace/helper/examples/oerasif0.cpp>


    #include <vector>

void

  vector< int > v( numbers, numbers + 6 );

  os_erase_if( v, odd );

  for ( vector< int >::iterator i = v.begin(); i != v.end(); ++i )
