More of a Minix question - anyone know about Minix inter-process messaging/open.c?

[summersab]

Here's what I'm doing. I've got a project to implement soft links in Minix. The first place I went was the file open.c (attached). Observe the do_open section at line 48. I'm trying to get a cstring that contains the path of the file being opened. My first instinct was

char* temp = m_in.name;

However, this doesn't appear to be working. Does anyone know how I can access the path of the file being opened and set it to a cstring? Thanks a bundle!
