Code Issues Releases Activity

Custom devoptab wrappers (part 1).

Browse source 
This commit implements a devoptab wrapper for Partition FS sections within NCAs, using code from pfs.c/h.

Other changes include:

* codebase: use NX_IGNORE_ARG macro where needed.

* hfs: slight tweaks to some of the static functions.

* pfs: slight tweaks to some of the static functions.
* pfs: use pfsIsValidContext() where needed.

* utils: update utilsInitializeResources() to use __system_argc and __system_argv variables from libnx.

* todo: update text file.
