Memory Allocation

Traffic Server provides five routines for allocating and freeing memory. These routines correspond to similar routines in the C library. For example, INKrealloc behaves like the C library routine realloc.

There are two main reasons for using the routines provided by Traffic Server. The first is portability: the Traffic Server API routines behave the same on all of Traffic Server’s supported platforms. For example, realloc does not accept an argument of NULL on some platforms. The second reason is that the Traffic Server routines actually track the memory allocations by file and line number. This tracking is very efficient, always turned on, and quite useful when tracking down memory leaks.

The memory allocation functions are:
