Member Function Documentation

void __gnu_cxx::free_list::_M_clear

(

)

This function just clears the internal Free List, and gives back all the memory to the OS.

size_t* __gnu_cxx::free_list::_M_get	(	size_t	__sz	)
throw	(	std::bad_alloc
	)

This function gets a block of memory of the specified size from the free list.

Parameters

__sz	The size in bytes of the memory required.

Returns

A pointer to the new memory block of size at least equal to that requested.

void __gnu_cxx::free_list::_M_insert ( size_t *  __addr ) throw ( )

Parameters

__addr

The pointer to the memory block that was given by a call to the _M_get function.
