Function
GLibopen
since: 2.6
Declaration [src]
int
g_open (
const gchar* filename,
int flags,
int mode
)
Description [src]
A wrapper for the POSIX open() function. The open() function is
used to convert a pathname into a file descriptor.
On POSIX systems file descriptors are implemented by the operating
system. On Windows, it’s the C library that implements open() and
file descriptors. The actual Win32 API for opening files is quite
different, see MSDN documentation for CreateFile(). The Win32 API
uses file handles, which are more randomish integers, not small
integers like file descriptors.
Because file descriptors are specific to the C library on Windows,
the file descriptor returned by this function makes sense only to
functions in the same C library. Thus if the GLib-using code uses a
different C library than GLib does, the file descriptor returned by
this function cannot be passed to C library functions like write()
or read().
See your C library manual for more details about open().

Parameters
filename-
Type:
const gchar*A pathname in the GLib file name encoding (UTF-8 on Windows).
The data is owned by the caller of the function. The value is a platform-native string, using the preferred OS encoding on Unix and UTF-8 on Windows. flags-
Type:
intAs in open().
mode-
Type:
intAs in open().
