PR_FREEIF
syntax #include <prmem.h> void pr_freeif(_ptr); parameter _ptr the address of memory to be returned to the heap.

PR_Free
syntax #include <prmem.h> void pr_free(void *ptr); parameter ptr a pointer to the memory to be freed.

PR_FreeLibraryName
syntax #include <prlink.h> void pr_freelibraryname(char *mem); parameters the function has this parameter: mem a reference to a character array that was previously allocated by the dynamic library runtime.

Memory Management Operations
memory allocation functions are: pr_malloc pr_calloc pr_realloc pr_free pr_malloc(), pr_calloc(), pr_realloc(), and pr_free() have the same signatures as their libc equivalents malloc(), calloc(), realloc(), and free(), and have the same semantics.
... (note that the argument type size_t is replaced by pruint32.) memory allocated by pr_malloc(), pr_calloc(), or pr_realloc() must be freed by pr_free().
... memory allocation macros macro versions of the memory allocation functions are available, as well as additional macros that provide programming convenience: pr_malloc pr_new pr_realloc pr_calloc pr_newzap pr_delete pr_freeif ...

when you are finished with them, you should free all the returned values using pr_free.
...when the callback function is finished with the string returned, the string should be freed with a call to pr_free.

Choosing the right memory allocator
pr_alloc() (do not use, no users and only exists in /security/; use pr_malloc() instead) pr_malloc() == pr_malloc pr_calloc() == pr_calloc pr_realloc() == pr_realloc pr_free() pr_new (pass in a struct to allocate its size) pr_newzap (same as pr_new, but zeros memory) pr_delete (pr_free() and also clears the pointer) pr_freeif special cases pr_smprintf(), pr_sprintf_append(), pr_vsmprintf() and pr_vsprintf_append() must be freed with pr_smprintf_free() pl_strdup(), pl_strndup() must be freed with pl_strfree() nscrt::strdup/nscrt::strndup must be ...

Dynamic Library Linking
library linking types these data types are defined for dynamic library linking: prlibrary prstaticlinktable library linking functions the library linking functions are: pr_setlibrarypath pr_getlibrarypath pr_getlibraryname pr_freelibraryname pr_loadlibrary pr_unloadlibrary pr_findsymbol pr_findsymbolandlibrary finding symbols defined in the main executable program pr_loadlibrary cannot open a handle that references the main executable program.

PRAddrInfo
typically, a praddrinfo object will be found via pr_getaddrinfobyname, iterated through using pr_enumerateaddrinfo, and finally freed with pr_freeaddrinfo.

PR GetAddrInfoByName
when no longer needed, this pointer must be destroyed with a call to pr_freeaddrinfo.

PR GetCanonNameFromAddrInfo
this pointer is invalidated once the praddrinfo structure is destroyed by a call to pr_freeaddrinfo.

PR_GetLibraryName
when it is no longer used, free it using pr_freelibraryname.

PR_GetLibraryPath
when it is no longer used, free it using pr_freelibraryname.
