Detailed Description

An object of type alloc_ct contains information about one allocated memory block.

Member Function Documentation

char const* libcwd::alloc_ct::description ( void  ) const
inline

A pointer to a description of the allocated memory block.

This is a character string that is the result of writing the second parameter of AllocTag() to an ostrstream.

References a_description.

location_ct const& libcwd::alloc_ct::location ( void  ) const
inline

The source file location that the allocator was called from.

Returns
a const location_ct reference corresponding to the place where the allocation was done.  Class location_ct describes a source file and line number location and in which function that location resides.

References M_location.

struct timeval const& libcwd::alloc_ct::time ( void  ) const
inline

The time at which this allocation was made.

Returns
the time at which the memory was allocated, as returned by a call to gettimeofday.

References a_time.

type_info_ct const& libcwd::alloc_ct::type_info ( void  ) const
inline

A reference to the type info of the pointer to the allocated memory block.

Returns
a reference to the static type_info_ct object that is returned by a call to type_info_of(p1).  Where p1 is the first parameter that was passed to AllocTag().

References type_info_ptr.
