debugfs_create_bool

DEBUGFS_CREATE_BOOL(9)					      The debugfs filesystem					    DEBUGFS_CREATE_BOOL(9)

NAME

       debugfs_create_bool - create a debugfs file that is used to read and write a boolean value

SYNOPSIS

       struct dentry * debugfs_create_bool(const char * name, mode_t mode, struct dentry * parent, u32 * value);

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.

       value
	   a pointer to the variable that the file should read to and write from.

DESCRIPTION

       This function creates a file in debugfs with the given name that contains the value of the variable value. If the mode variable is so set,
       it can be read from, and written to.

       This function will return a pointer to a dentry if it succeeds. This pointer must be passed to the debugfs_remove 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.

       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.
