NAME

luaL_checklstring — checks whether the function argument is a string, function indicator [-0, +0, v]

SYNOPSIS

#include <lauxlib.h>

const char *
luaL_checklstring(lua_State *L, int narg, size_t *l);

DESCRIPTION

luaL_checklstring() checks whether the function argument narg is a string and returns this string; if l is not NULL fills *l with the string's length.

This function uses lua_tolstring(3) to get its result, so all conversions and caveats of that function apply here.
