+  SYNOPSIS
+
+  glfs_fsetattr: Function to set attributes.
+  glfs_setattr: Function to set attributes
+
+  DESCRIPTION
+
+  The functions are used to set attributes on the file.
+
+  PARAMETERS
+
+  @glfs_fsetattr
+
+     @glfd: The fd of the file for which the attributes are to be set,
+            this fd is returned by glfs_open/glfs_create.
+
+  @glfs_setattr
+
+         @fs: File object.
+
+         @path: The path of the file that is being operated on.
+
+         @follow: Flag used to resolve symlink.
+
+
+  @stat: Struct that has information about the file.
+
+  @valid: This is the mask bit, that accepts GFAPI_SET_ATTR* masks.
+          Refer glfs.h to see the mask definitions.
+
+  Both functions are similar in functionality, just that the
+  func setattr() uses file path whereas the func fsetattr()
+  uses the fd.
+
+  RETURN VALUES
+  0:  Successful completion
+  <0: Failure. @errno will be set with the type of failure
