set_table_userdata Subroutine

private subroutine set_table_userdata(val, L, thandle, key, pos)

Uses

  • proc~~set_table_userdata~~UsesGraph proc~set_table_userdata set_table_userdata iso_c_binding iso_c_binding proc~set_table_userdata->iso_c_binding

Put user-data pointer into a table.

Arguments

Type IntentOptional Attributes Name
type(c_ptr), intent(in) :: val

Pointer to set in the table.
type(flu_State) :: L

Handle to the Lua script.
integer, intent(in) :: thandle

Handle to the table to look the value up in.
character(len=*), intent(in), optional :: key

Name of the entry to set.

Key and pos are both optional, however at least one of them has to be supplied. The key takes precedence over the pos if both are given.
integer, intent(in), optional :: pos

Position of the entry to set in the table.

It allows the access to unnamed arrays in the Lua tables.
