DEPRECATED syscalls_fileAdd => syscalls_fileOpen

GETFROMSTACK(ustack, unsigned int *, h, 0);
GETFROMSTACK(ustack, oid_t *, oid, 1);
GETFROMSTACK(ustack, unsigned int, mode, 2);

Adds file given by oid to process resources. Added process resource is identified by handle returned in h variable. The access mode is set to mode.


syscalls_fileOpen (syscalls_sys_open)

GETFROMSTACK(ustack, const char *, filename, 0);
GETFROMSTACK(ustack, int, oflag, 1);

DEPRECATED syscalls_fileSet => syscalls_fileRead, syscalls_fileWrite

GETFROMSTACK(ustack, unsigned int, h, 0);
GETFROMSTACK(ustack, char, flags, 1);
GETFROMSTACK(ustack, oid_t *, oid, 2);
GETFROMSTACK(ustack, offs_t, offs, 3);
GETFROMSTACK(ustack, unsigned, mode, 4);

Updates file parameters for file given by resource handle h.


DEPRECATED syscalls_fileGet => syscalls_fileRead, syscalls_fileWrite

GETFROMSTACK(ustack, unsigned int, h, 0);
GETFROMSTACK(ustack, int, flags, 1);
GETFROMSTACK(ustack, oid_t *, oid, 2);
GETFROMSTACK(ustack, offs_t *, offs, 3);
GETFROMSTACK(ustack, unsigned *, mode, 4);

Retrieves file parameters for file given by resource handle h.


DEPRECATED syscalls_fileRemove => syscalls_fileClose

GETFROMSTACK(ustack, unsigned int, h, 0);

Removes file given by h from resources of calling process.
