DEBUGFS_CREATE_U32_A(9) The debugfs filesystem DEBUGFS_CREATE_U32_A(9)NAMEdebugfs_create_u32_array - create a debugfs file that is used to read
u32 array.
SYNOPSIS
struct dentry * debugfs_create_u32_array(const char * name,
umode_t mode,
struct dentry * parent,
u32 * array, u32 elements);
ARGUMENTS
name
a pointer to a string containing the name of the file to create.
mode
the permission that the file should have.
parent
a pointer to the parent dentry for this file. This should be a
directory dentry if set. If this parameter is NULL, then the file
will be created in the root of the debugfs filesystem.
array
u32 array that provides data.
elements
total number of elements in the array.
DESCRIPTION
This function creates a file in debugfs with the given name that
exports array as data. If the mode 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.
The function returns a pointer to dentry on success. If debugfs is not
enabled in the kernel, the value -ENODEV will be returned.
