DEBUGFS_CREATE_U32_A(9)               The debugfs filesystem              DEBUGFS_CREATE_U32_A(9)



NAME
       debugfs_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.
