18.2.2 Memory Management
Internally, libltdl maintains a list of loaded modules and
symbols on the heap. If you find that you want to use it with a project
that has an unusual memory management API, or if you simply want to
use a debugging `malloc', libltdl provides hook functions
for you to set the memory routines it should call.
The way to use these hooks is to point them at the memory allocation
routines you want libltdl to use before calling any of its
lt_dlmalloc = (lt_prt_t (*) PARAMS((size_t))) mymalloc;
lt_dlfree = (void (*) PARAMS((lt_ptr_t))) myfree;
Notice that the function names need to be cast to the correct type
before assigning them to the hook symbols. You need to do this because
the prototypes of the functions you want libltdl to use will vary
slightly from libltdls own function pointer types--
lt_ptr_t for compatibility with K&R
compilers, for example.
