+# NAME
+
+term\_ensurefg - ensure current process is in the foreground job if needed
+
+# SYNOPSIS
+
+    #include <limb/term.h>
+
+```pre hl
+int term_ensurefg(int <em>fd</em>)
+```
+
+# DESCRIPTION
+
+The `term_ensurefg`() function will make sure the current process is in the
+foreground process group of its controlling terminal, which must be referred to
+by `fd`.
+
+! NOTE:
+! To do so, the *SIGTTOU* signal will be ignored during the execution of the
+! function (so it doesn't get send and blocks the process whilst setting the
+! terminal foreground process group) then restored to its original handling
+! state.
+
+# RETURN VALUE
+
+The `term_ensurefg`() function returns 1 on success, otherwise it returns 0 and
+sets `errno` to indicate the error.
+
+# ERRORS
+
+The `term_ensurefg`() function may fail and set `errno` for any of the errors
+described for [tcsetpgrp](3) except *EINVAL* and *EPERM*.
