get_table_logical Subroutine

private subroutine get_table_logical(val, ErrCode, L, thandle, key, pos, default)

Retrieve a logical value from a table.

Arguments

Type IntentOptional Attributes Name
logical, intent(out) :: val

Value of the table entry if it exists.

integer, intent(out) :: ErrCode

Error code to indicate what kind of problem might have occured.

type(flu_State) :: L

Handle to the Lua script.

integer, intent(in), optional :: thandle

Handle to the table to look the value up in.

character(len=*), intent(in), optional :: key

Name of the entry to look for.

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 look for in the table.

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

logical, intent(in), optional :: default

Some default value, that should be used, if the variable is not set in the Lua script.
