.SH "NAME"
debugfs_create_u32_array \- create a debugfs file that is used to read u32 array\&.
.SH "SYNOPSIS"
.HP \w'struct\ dentry\ *\ debugfs_create_u32_array('u
.BI "struct dentry * debugfs_create_u32_array(const\ char\ *\ " "name" ", umode_t\ " "mode" ", struct\ dentry\ *\ " "parent" ", u32\ *\ " "array" ", u32\ " "elements" ");"
.SH "ARGUMENTS"
.PP
\fIconst char * name\fR
.RS 4
a pointer to a string containing the name of the file to create\&.
.RE
.PP
\fIumode_t mode\fR
.RS 4
the permission that the file should have\&.
.RE
.PP
\fIstruct dentry * parent\fR
.RS 4
a pointer to the parent dentry for this file\&. This should be a directory dentry if set\&. If this parameter is
\fBNULL\fR, then the file will be created in the root of the debugfs filesystem\&.
.RE
.PP
\fIu32 * array\fR
.RS 4
u32 array that provides data\&.
.RE
.PP
\fIu32 elements\fR
.RS 4
total number of elements in the array\&.
.RE
.SH "DESCRIPTION"
.PP
This function creates a file in debugfs with the given name that exports
\fIarray\fR
as data\&. If the
\fImode\fR
variable is so set it can be read from\&. Writing is not supported\&. Seek within the file is also not supported\&. Once array is created its size can not be changed\&.
.PP
The function returns a pointer to dentry on success\&. If debugfs is not enabled in the kernel, the value \-\fBENODEV\fR
will be returned\&.
