.TH "DEBUGFS_CREATE_DIR" "9" "09 October 2005" "" ""

.SH NAME
debugfs_create_dir \- create a directory in the debugfs filesystem
.SH SYNOPSIS
"SYNOPSIS"
.sp
\fB
.sp
struct dentry * debugfs_create_dir  (const char * \fIname\fB, struct dentry * \fIparent\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIname\fB\fR
a pointer to a string containing the name of the directory to
create.
.TP
\fB\fIparent\fB\fR
a pointer to the parent dentry for this file.  This should be a
directory dentry if set.  If this paramater is NULL, then the
directory will be created in the root of the debugfs filesystem.
.SH "DESCRIPTION"
.PP
This function creates a directory in debugfs with the given name.
.PP
This function will return a pointer to a dentry if it succeeds.  This
pointer must be passed to the \fBdebugfs_remove\fR function when the file is
to be removed (no automatic cleanup happens if your module is unloaded,
you are responsible here.)  If an error occurs, NULL will be returned.
.PP
If debugfs is not enabled in the kernel, the value -ENODEV will be
returned.  It is not wise to check for this value, but rather, check for
NULL or !NULL instead as to eliminate the need for #ifdef in the calling
code.
