Creating or modifying a PST file?

[kartikeysemwal]

Hi, thanks for creating the library. My requirement is to create or modify PST. Is your library able to do this task? Also, I successfully built the libpff repo and started writing some basic C++ code to get used to the functions. When using the function libpff_item_get_utf8_display_name_size, I am getting error Error C4996 'libpff_item_get_entry_value_utf8_string_size': was declared deprecated. Can you please provide some helpful suggestions and recommended practices to get started with this library.

no this project focuses on reading only

Can you please provide some helpful suggestions and recommended practices to get started with this library.

The interface is not that complex. Looks like you figured out most of it already. Also see https://github.com/libyal/libpff/wiki/C-development and the pfftools as example code.

Regarding the depredation warning have a look at https://github.com/libyal/libpff/blob/main/include/libpff.h.in#L1075

Thanks for the quick follow up. I will take a look. Thanks
