Member Function Documentation

◆ _M_clear()

void __gnu_cxx::free_list::_M_clear ( )

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

◆ _M_get()

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

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

Parameters
__szThe size in bytes of the memory required.
Returns
A pointer to the new memory block of size at least equal to that requested.

◆ _M_insert()

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

This function returns the block of memory to the internal free list.

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