First of all, you're using FreeType internals, which means your program
isn't guaranteed to work with succesive versions of the library..

However, it is true that there's currently no high-level interface to
retrieve names from a SFNT-based font file (TrueType & OpenType). This
will come, but probably a bit later..

What does "fails on memory" exactly means ??

A bug, you can use face->name_tables.numNameRecords instead for the moment
until this is fixed..

What do you mean. Modules are pretty internal to the engine. They will be
described later but I have no intention to document them fully for now.

What kind of things interest you in the "psnames" module ?

Best,
